Registration No.: 333-278671

19,800,000 shares of Common Stock

Pre-funded Warrants to Purchase 30,200,000 Shares of Common Stock

Up to 30,200,000 shares of Common Stock underlying the Pre-funded Warrants

We are offering, on a firm commitment basis, 19,800,000 shares of our common stock, par value $0.00001 per share at a public offering price of $0.10 per share.

We are also offering pre-funded warrants (the "Pre-funded Warrants") to purchase up to 30,200,000 shares of common stock to those purchasers whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, in lieu of shares of common stock that would result in beneficial ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. Each Pre-funded Warrant is exercisable for one share of our common stock and has an exercise price of $0.00001 per share. For each Pre-funded Warrant that we sell, the number of shares of common stock we are offering will be reduced on a one-for-one basis.

Pursuant to this prospectus, we are also offering the shares of common stock issuable upon the exercise of the Pre-funded Warrants offered hereby.

Our common stock is listed on The Nasdaq Capital Market ("Nasdaq"), under the symbol "CYN." On April 23, 2024, the last reported sale price of our common stock was $0.1140 per share. We do not intend to list the Pre-funded Warrants offered pursuant to this prospectus on any national securities exchange or other nationally recognized trading system.

The final public offering price of the shares of our common stock or Pre-funded Warrants will be determined through negotiation between us and the underwriter, based upon a number of factors, including our history and our prospects, the industry in which we operate, our past and present operating results, the previous experience of our executive officers and the general condition of the securities markets at the time of this offering.

We have granted Aegis Capital Corp., as "Underwriter", an option, exercisable for 45 days from the closing date of this offering, to purchase up to 7,500,000 additional shares of common stock, representing 15% of the shares of common stock and/or Pre-funded Warrants sold in the offering.

Investing in our securities involves a high degree of risk. See "Risk Factors" beginning on page 7 of this prospectus to read about factors you should consider before investing in our securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

RISK FACTORS

An investment in our securities involves a high degree of risk. You should carefully consider the following risks and all of the other information contained or incorporated by reference in this prospectus before deciding whether to invest in our securities , including the risks and uncertainties described below and under the caption "Risk Factors" in our most recently filed Annual Report on Form 10-K and Quarterly Report on Form 10-Q filed with the SEC, in each case as these risk factors are amended or supplemented by subsequent Annual Reports on Form 10-K or Quarterly Reports on Form 10-Q. Our business, financial condition, results of operations and future prospects may be adversely affected as a result of such risks. In such an event, the market price of our common stock could decline, and you could lose part or all of your investment.

Risks Relating to this Offering and Ownership of Our Securities

Our management has concluded there is substantial doubt as to our ability to continue as a going concern if we are not able to raise sufficient capital.

We incurred net losses of $22.8 million and $19.2 million for the years ended December 31, 2023, and 2022, respectively. As of December 31, 2023, we had $3.6 million of cash. Based on cash flow projections from operating and financing activities and the existing balance of cash and short-term investments, management is of the opinion that the Company has insufficient funds for sustainable operations, and it may not be able to meet its payment obligations from operations and related commitments, if the Company is not able to raise sufficient capital or to allow the Company to continue as a going concern, for the next year. Our consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets and liabilities that may result in the Company not being able to continue as a going concern.

The Company's ability to continue as a going concern is dependent on management's ability to successfully execute its business plan, which includes increasing revenue while controlling operating costs and expenses to generate positive operating cash flows and obtaining funds from outside sources of financing to generate positive financing cash flows.

There can be no assurance that any such measures will be successful. We currently do not generate substantial revenue from product sales. Accordingly, we expect to rely primarily on equity and/or debt financings to fund our continued operations. Our ability to raise additional funds will depend, in part, on the success of our product development activities, and other events or conditions that may affect our value or prospects, as well as factors related to financial, economic and market conditions, many of which are beyond our control. There can be no assurances that sufficient funds will be available to us when required or on acceptable terms, if at all. Even if successful in raising new capital, we could be limited in the amount of capital we raise due to investor demand restrictions placed on the amount of capital we raise or other reasons. For example, if we seek to raise funds utilizing our effective Registration Statement on Form S-3, we are subject to the limitations set forth in Instruction I.B.6 of Form S-3), which limits the amount we can raise to one-third of our public float, less shares sold in the prior twelve months under I.B.6. Accordingly, management has concluded that these plans do not alleviate substantial doubt about the Company's ability to continue as a going concern.

If we are not successful in improving our liquidity position, we may be required to significantly delay, scale back, or discontinue the development or commercialization of our product candidates, pursue the sale of our company to a third party at a price that may result in a loss on investment for our stockholders, or file for bankruptcy or cease operations altogether. Any of these events could have a material adverse effect on our business, operating results and prospects.

The Pre-funded Warrants will not be listed or quoted on any exchange.

There is no established public trading market for the Pre-funded Warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the Pre-funded Warrants on any national securities exchange or other nationally recognized trading system, including Nasdaq. Without an active market, the liquidity of the Pre-funded Warrants will be limited.

Except as otherwise provided in the Pre-funded Warrants, holders of Pre-funded Warrants purchased in this offering will have no rights as stockholders until such holders exercise their Pre-funded Warrants and acquire our common stock.

Except as otherwise provided in the Pre-funded Warrants, until holders of Pre-funded Warrants acquire our common stock upon exercise of the Pre-funded Warrants, holders of Pre-funded Warrants will have no rights with respect to our common stock underlying such Pre-funded Warrants. Upon exercise of the Pre-funded Warrants, the holders will be entitled to exercise the rights of a holder of our common stock only as to matters for which the record date occurs after the exercise date.

The Pre-funded Warrants are speculative in nature.

The Pre-funded Warrants offered hereby do not confer any rights of ownership of our shares of common stock on their holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire shares of common stock at a fixed price. Specifically, commencing on the date of issuance, holders of the Pre-funded Warrants may acquire shares of common stock issuable upon exercise of such warrants at an exercise price of $0.0001 per share of common stock. Moreover, following this offering, the market value of the Pre-funded Warrants is uncertain, and there can be no assurance that the market value of the Pre-funded Warrants will equal or exceed their public offering price.

We are not in compliance with The NASDAQ Capital Market $1.00 minimum bid price requirement and failure to maintain compliance with this standard could result in delisting and adversely affect the market price and liquidity of our common stock.

Our common stock is currently traded on The NASDAQ Capital Market under the symbol "CYN". If we fail to meet any of the continued listing standards of The NASDAQ Capital Market, our common stock will be delisted from The NASDAQ Capital Market. These continued listing standards include specifically enumerated criteria, such as a $1.00 minimum closing bid price. On August 24, 2023, we received a letter from The NASDAQ Stock Market advising that the Company did not meet the minimum $1.00 per share bid price requirement for continued inclusion on The NASDAQ Capital Market pursuant to NASDAQ Marketplace Listing Rule 5550(a)(2). To demonstrate compliance with this requirement, the closing bid price of our common stock needs to be at least $1.00 per share for a minimum of 10 consecutive business days before February 20, 2024. On February 21, 2024, Nasdaq granted the Company an additional 180-day extension to continue its listing on the Nasdaq Capital Market. The Company was given until August 19, 2024 to regain compliance with Nasdaq's $1 minimum bid price per share requirement.

While we intend to regain compliance with the minimum bid price rule, there can be no assurance that we will be able to maintain continued compliance with this rule or the other listing requirements of The NASDAQ Capital Market. If we were unable to meet these requirements, we would receive another delisting notice from the Nasdaq Capital Market for failure to comply with one or more of the continued listing requirements. If our common stock were to be delisted from The NASDAQ Capital Market, trading of our common stock most likely will be conducted in the over-the-counter market on an electronic bulletin board established for unlisted securities such as the OTC Markets or in the "pink sheets." Such a downgrading in our listing market may limit our ability to make a market in our common stock and which may impact purchases or sales of our securities.

Our management will have broad discretion over the use of the net proceeds from this offering.

We currently intend to use the net proceeds from the sale of our securities under this offering for general corporate purposes, including working capital. We have not reserved or allocated specific amounts for any of these purposes and we cannot specify with certainty how we will use the net proceeds (see "Use of Proceeds"). Accordingly, our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. We may use the net proceeds for corporate purposes that do not increase our operating results or market value.

Future sales of our common stock could lower our stock price and dilute existing stockholders.

We may, in the future, sell additional shares of common stock in subsequent public or private offerings. We cannot predict the size or terms of future issuances of our common stock or the effect, if any, that future sales and issuances of shares of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock, or the perception that such sales could occur, may adversely affect prevailing market prices for our common stock. In addition, these sales may be dilutive to existing stockholders.

We have not paid cash dividends in the past and do not expect to pay dividends in the future. Any return on investment may be limited to the value of our common stock, which may decrease in value.

We have never paid cash dividends on our common stock and do not anticipate doing so in the foreseeable future. On September 29, 2023, our Board of Directors declared a one-time special dividend of 10% on our issued and outstanding shares of our common stock to holders of record on October 23, 2023. The payment of dividends on our common stock will depend on earnings, financial condition and other business and economic factors affecting us at such time as our board of directors may consider relevant. If we do not pay dividends, our common stock may be less valuable because a return on your investment will only occur if our stock price appreciates.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

All statements in this prospectus and the documents incorporated by reference that are not historical facts should be considered "Forward Looking Statements" within the meaning of the "Safe Harbor" provisions of the Private Securities Litigation Reform Act of 1995. Such statements involve known and unknown risks, uncertainties and other factors that may cause actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

These forward-looking statements are based upon the current beliefs and expectations of our management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are difficult to predict and generally beyond our control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. Actual results may differ materially from the anticipated results discussed in these forward-looking statements.

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the securities we are offering will be approximately $4.4 million (or approximately $5.1 million if the underwriter exercises in full its over-allotment option), after deducting the estimated underwriting discounts and commissions and estimated offering costs payable by us. We intend to use the net proceeds we receive from this offering for general corporate purposes, including working capital.

As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Accordingly, our management will have broad discretion in the timing and application of these proceeds.

DESCRIPTION OF CAPITAL STOCK

We are authorized to issue up to 200,000,000 shares of common stock, par value $0.00001 per share, and 10,000,000 shares of preferred stock, par value $0.00001 per share.

The following is a summary of the material terms of our capital stock and certain provisions of our certificate of incorporation and bylaws. Since the terms of our certificate of incorporation and bylaws, and Delaware law, are more detailed than the general information provided below, you should only rely on the actual provisions of those documents and Delaware law. If you would like to read those documents, they are on file with the SEC, as described under the heading "Where You Can Find More Information" below. The summary below is also qualified by provisions of applicable law.

Common Stock

Our certificate of incorporation, as amended and restated ("Certificate of Incorporation") authorize us to issue up to 200,000,000 shares of common stock, $0.00001 par value. Each holder of our common stock is entitled to one (1) vote for each share held of record on all voting matters we present for a vote of stockholders, including the election of directors. Holders of common stock have no cumulative voting rights or preemptive rights to purchase or subscribe for any stock or other securities, and there are no conversion rights or redemption or sinking fund provisions with respect to our common stock. All shares of our common stock are entitled to share equally in dividends from sources legally available when, and if, declared by our Board of Directors.

Our Board of Directors is authorized to issue additional shares of common stock not to exceed the amount authorized by the Certificate of Incorporation, on such terms and conditions and for such consideration as the Board may deem appropriate without further stockholder action.

In the event of our liquidation or dissolution, all shares of our common stock are entitled to share equally in our assets available for distribution to stockholders. However, the rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of preferred stock that have been issued or shares of preferred stock that our Board of Directors may decide to issue in the future.

Pre-funded Warrants to be issued in this offering

The following summary of certain terms and conditions of the Pre-funded Warrants is not complete and is subject to, and qualified in its entirety by, the provisions of Pre-funded Warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Pre-funded Warrant for a complete description of the terms and conditions of the Pre-funded Warrants.

General

The term "pre-funded" refers to the fact that the purchase price of the Pre-funded Warrants in this offering includes almost the entire exercise price that will be paid under the Pre-funded Warrants, except for a nominal remaining exercise price of $0.00001. The purpose of the Pre-funded Warrants is to enable investors that may have restrictions on their ability to beneficially own more than 4.99% (or, at the election of the holder, 9.99%) of our outstanding common stock following the consummation of this offering the opportunity to invest capital into the Company without triggering their ownership restrictions, by receiving Pre-funded Warrants in lieu of shares of our common stock which would result in such ownership of more than 4.99% (or, at the election of the holder, 9.99%), and receiving the ability to exercise their option to purchase the shares underlying the Pre-funded Warrants at a nominal price at a later date.

Form

The Pre-funded Warrants will be issued as individual warrant agreements to the investors. You should review the form of Pre-funded Warrant, filed as an exhibit to the registration statement of which this prospectus forms a part, for a complete description of the terms and conditions applicable to the Pre-funded Warrants.

Exercisability

The Pre-funded Warrants are exercisable at any time after their original issuance. The Pre-funded Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full in immediately available funds for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as described below). A holder (together with its affiliates) may not exercise any portion of the Pre-funded Warrant to the extent that the holder would own more than 4.99% (or, at the election of the holder, 9.99%) of the outstanding common stock immediately after exercise, except that upon at least 61 days' prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder's Pre-funded Warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Pre-funded Warrants.

Duration and Exercise Price

The exercise price per whole share of our common stock purchasable upon the exercise of the Pre-funded Warrants is $0.00001 per share of common stock. The Pre-funded Warrants will be immediately exercisable and may be exercised at any time until the Pre-funded Warrants are exercised in full.

Cashless Exercise

At any time after the issuance of the Pre-funded Warrants, in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may instead receive upon such exercise (either in whole or in part) only the net number of shares of common stock determined according to a formula set forth in the Pre-funded Warrants. Notwithstanding anything to the contrary, in the event we do not have or maintain an effective registration statement, there are no circumstances that would require us to make any cash payments or net cash settle the Pre-funded Warrants to the holders.

Transferability

Subject to applicable laws, the Pre-funded Warrants may be offered for sale, sold, transferred or assigned at the option of the holder upon surrender of the Pre-funded Warrants to us together with the appropriate instruments of transfer.

Exchange Listing

There is no established trading market for the Pre-funded Warrants and we do not plan on applying to list the Pre-funded Warrants on The Nasdaq Capital Market any other national securities exchange or any other nationally recognized trading system.

Fundamental Transactions

If, at any time while the Pre-funded Warrants are outstanding, (1) we consolidate or merge with or into another corporation whether or not the Company is the surviving corporation, (2) we sell, lease, license, assign, transfer, convey or otherwise dispose of all or substantially all of our assets, or any of our significant subsidiaries, (3) any purchase offer, tender offer or exchange offer (whether by us or another individual or entity) is completed pursuant to which holders of our common stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of our common stock, (4) we consummate a securities purchase agreement or other business combination with another person or entity whereby such other person or entity acquires more than 50% of our outstanding common stock, or (5) we effect any reclassification or recapitalization of our common stock or any compulsory exchange pursuant to which our common stock is converted into or exchanged for other securities, cash or property, or each, a "Fundamental Transaction," then upon any subsequent exercise of Pre-funded Warrants, the holders thereof will have the right to receive the same amount and kind of securities, cash or property as they would have been entitled to receive upon the occurrence of such Fundamental Transaction if they had been, immediately prior to such Fundamental Transaction, the holder of the number of shares of common stock then issuable upon exercise of those Pre-funded Warrants, and any additional consideration payable as part of the Fundamental Transaction.

Rights as a Stockholder

Except by virtue of such holder's ownership of shares of our common stock or as otherwise set forth in the Pre-funded Warrants, the holder of a Pre-funded Warrant does not have the rights or privileges of a holder of our common stock, including any voting rights, until the holder exercises the Pre-funded Warrant.

Preferred Stock

Our Certificate of Incorporation authorize us to issue up to 10,000,000 shares of preferred stock, $0.00001 par value. Our Board of Directors is authorized, without further action by the stockholders, to issue shares of preferred stock and to fix the designations, number, rights, preferences, privileges, and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences and sinking fund terms. We believe that the Board of Directors' power to set the terms of, and our ability to issue preferred stock, will provide flexibility in connection with possible financing or acquisition transactions in the future. The issuance of preferred stock, however, could adversely affect the voting power of holders of common stock and decrease the amount of any liquidation distribution to such holders. The presence of outstanding preferred stock could also have the effect of delaying, deterring, or preventing a change in control of our Company.

Outstanding Warrants

As of April 23, 2024, we had 7,236,776 outstanding warrants with a weighted average exercise price of $2.82 per share, with a weighted average remaining life of 5 years.

Outstanding Options

As of April 23, 2024, we have 17,082,399 outstanding options with a weighted average exercise price of $1.02 per share, with a weighted average remaining contractual life of 7.04 years.

Restricted Stock Units (RSU)

As of April 23, 2024, we have 160,992 outstanding RSUs.

These registration rights are subject to specified conditions and limitations, including, but not limited to, the right of the underwriters to limit the number of shares included in any such offering under certain circumstances, but not below 30% of the total amount of securities included in such offering.

Our second amended and restated investors' rights agreement contains customary cross-indemnification provisions, under which we are obligated to indemnify holders of registrable securities in the event of material misstatements or omissions in the registration statement attributable to us, and they are obligated to indemnify us for material misstatements or omissions attributable to them.

The registration rights granted under the second amended and restated investor rights agreement will terminate on the earlier of the closing of a deemed liquidation event as defined in our second amended and restated certificate of incorporation, such time as Rule 144 is available for the sale of all of the holders' shares without limitation during a three-month period and the fifth anniversary of the completion of this offering.

On May 31, 2023, we filed a registration statement on Form S-3 which included an aggregate of 7,721,781 shares of our common stock held by the parties to the second amended and restated investor rights agreement.

Anti-Takeover Provisions

Certificate of Incorporation and Bylaw Provisions

Our amended and restated certificate of incorporation and our amended and restated bylaws will include a number of provisions that may have the effect of deterring hostile takeovers or delaying or preventing changes in control of our management team, including the following:

Classified Board. Our fifth amended and restated certificate of incorporation and amended and restated bylaws provide that our board of directors will be classified into three classes of directors, each of which will hold office for a three-year term. In addition, directors may only be removed from the board of directors for cause and only by the approval of two-thirds of the combined vote of our then outstanding shares of common stock. A third party may be discouraged from making a tender offer or otherwise attempting to obtain control of us as it is more difficult and time consuming for stockholders to replace a majority of the directors on a classified board of directors.

Supermajority Approvals. Our amended and restated bylaws require the approval of two-thirds of the combined vote of our then-outstanding shares of our common stock to amend our bylaws. This will have the effect of making it more difficult to amend our amended and restated bylaws to remove or modify certain provisions.

Advance Notice Requirements for Stockholder Proposals and Director Nominations. Our amended and restated bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at any meeting of stockholders. Our amended and restated bylaws will also specify certain requirements regarding the form and content of a stockholder's notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our meetings of stockholders.

Issuance of Undesignated Preferred Stock. Our board of directors has the authority, without further action by the holders of our common stock, to issue up to 10,000,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by the board of directors. The existence of authorized but unissued shares of preferred stock will enable our board of directors to render more difficult or discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest, or otherwise.

Issuance of Unissued Stock. Our shares of unissued common stock are available for future issuance without stockholder approval, subject to certain protections afforded to our preferred stock pursuant to our certificate of incorporation, as amended and restated. We may utilize these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, to facilitate corporate acquisitions, payment as a dividend on the capital stock or as equity compensation to our service providers under our equity compensation plans. The existence of unissued and unreserved common stock may enable our board of directors to issue shares to persons friendly to current management thereby protecting the continuity of our management. Also, if we issue additional shares of our authorized, but unissued, common stock, these issuances will dilute the voting power and distribution rights of our existing common stockholders.

Delaware Law

We are governed by the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a public Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

●	the business combination or transaction which resulted in the stockholder becoming an interested stockholder was approved by the board of directors prior to the time that the stockholder became an interested stockholder;

●

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding shares owned by directors who are also officers of the corporation and shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

●

at or subsequent to the time the stockholder became an interested stockholder, the business combination was approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

In general, Section 203 defines a "business combination" to include mergers, asset sales and other transactions resulting in financial benefit to a stockholder and an "interested stockholder" as a person who, together with affiliates and associates, owns, or within three years did own, 15% or more of the corporation's outstanding voting stock. These provisions may have the effect of delaying, deferring or preventing changes in control of our company.

Choice of Forum

Our amended and restated certificate of incorporation provide that unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty by any of our directors, officers or other employees to us or our stockholders; any action asserting a claim against the Company, our directors or officer or employees directors arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or amended and restated bylaws or any other action asserting a claim against us our directors or officers or employees that is governed by the internal affairs doctrine. This choice of forum provision does not apply to actions brought to enforce a duty or liability created by the Exchange Act or any other claim for which federal courts have exclusive jurisdiction.

Furthermore, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. We intend for this provision to apply to any complaints asserting a cause of action under the Securities Act despite the fact that Section 22 of the Securities Act creates concurrent jurisdiction for the federal and state courts over all actions brought to enforce any duty or liability created by the Securities Act or the rules and regulations promulgated thereunder. The enforceability of similar choice of forum provisions in other companies' certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions in our certificate of incorporation to be inapplicable or unenforceable.

Limitations of Liability and Indemnification

Our Certificate of Incorporation limits the liability of directors to the maximum extent permitted by the DGCL. The DGCL provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors.

Our bylaws, as amended, provide that we will indemnify our directors and officers to the fullest extent permitted by law, and may indemnify employees and other agents. Our bylaws also provide that we are obligated to advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding.

Our bylaws, as amended, subject to the provisions of the DGCL, contain provisions which allow the corporation to indemnify any person against liabilities and other expenses incurred as the result of defending or administering any pending or anticipated legal issue in connection with service to us if it is determined that person acted in good faith and in a manner which he or she reasonably believed was in the best interest of the corporation. Insofar as indemnification for liabilities arising under the Securities Act of 1933 as amended, or the Securities Act, may be permitted to our directors, officers and controlling persons, we have been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

The limitation of liability and indemnification provisions in our bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might provide a benefit to us and our stockholders. Our results of operations and financial condition may be harmed to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

At present, there is no pending litigation or proceeding involving any of our directors or officers as to which indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification.

UNDERWRITING

Aegis has agreed to act as our exclusive underwriter in connection with this offering. Under the terms of an underwriting agreement, which is filed as an exhibit to the registration statement, we have agreed to sell to the Underwriter and the Underwriter has agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the following number of shares of common stock and Pre-funded Warrants:

Underwriter		Number of Shares		Number of Pre-funded Warrants
Aegis Capital Corp.		19,800,000		30,200,000

The underwriting agreement provides that the Underwriter's obligation to purchase shares of common stock and Pre-funded Warrants depends on the satisfaction of the conditions contained in the underwriting agreement including:

●	the representations and warranties made by us to the underwriter are true;

●	there is no material change in our business or the financial markets; and

●	we deliver customary closing documents to the underwriter.

The Underwriter has agreed to purchase all of the shares of common stock and Pre-funded Warrants offered by this prospectus (other than those covered by the over-allotment option described below), if any are purchased under the underwriting agreement.

The Underwriter is offering the shares of common stock and Pre-funded Warrants subject to various conditions and may reject all or part of any order. The Underwriter has advised us that it proposes to offer the shares of common stock and Pre-funded Warrants directly to the public at the public offering price per share and Pre-funded Warrant, as applicable, that appears on the cover page of this prospectus supplement. In addition, the Underwriter may offer some of the common shares to other securities dealers at such price less a concession of $0.0035 per share. After the shares of common stock are released for sale to the public, the Underwriter may change the offering price and other selling terms at various times.

Over-Allotment Option

We have granted the Underwriter an over-allotment option. This option, which is exercisable for up to forty-five (45) days after the closing of the offering, permits the Underwriter to purchase a maximum of 7.500,000 additional shares of common stock (i.e., up to 15% of the shares of common stock and/or Pre-funded Warrants sold in this offering) from us to cover over-allotments, if any. The purchase price to be paid per additional share of common stock will be equal to the public offering price per share of common stock, less the underwriting discount. We will be obligated, pursuant to the option, to sell these additional shares of common stock to the underwriter to the extent the option is exercised. If any additional shares of common stock are purchased, the Underwriter will offer the additional shares on the same terms as those on which the other shares of common stock are being offered hereunder.

Underwriting Discounts and Expenses

The following table shows the per share and total underwriting discounts we will pay to Aegis. These amounts are shown assuming both no exercise and full exercise of the underwriter's option to purchase additional securities.

Underwriter Discounts and Expenses

We have engaged Aegis as our exclusive underwriter and book running manager in connection with this offering. Under the terms of an underwriting agreement, which is filed as an exhibit to the registration statement, we have agreed to sell to the Underwriter and the Underwriter has agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus, the following number of shares of common stock and Pre-funded Warrants:

		Per Share of Common Stock			Per Pre-Funded Warrant			Total with no Over-Allotment			Total with Over-Allotment
Public offering price		$	0.10			$	0.09999			$	4,999,685			$	5,750,000
Underwriting discounts and commissions (7.0%)(1)		$	0.007			$	0.00700			$	349,978			$	402,500
Proceeds, before expenses, to us		$	0.093			$	0.09299			$	4,649,707			$	5,347,500

(1)	We have agreed to pay up to $75,000 of the Underwriter's accountable expenses relating to the offering, including for road show, diligence, and legal expenses. We estimate the total expenses payable by us for this offering, excluding the Underwriter fees and expenses, will be approximately $180,738

Stabilization

In accordance with Regulation M under the Exchange Act, the Underwriter may engage in activities that stabilize, maintain or otherwise affect the price of our common stock, including short sales and purchases to cover positions created by short positions, stabilizing transactions, syndicate covering transactions, penalty bids and passive market making.

●

Short positions involve sales by the underwriter of shares of common stock in excess of the number of shares the underwriter is obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of shares involved in the sales made by the underwriter in excess of the number of shares they are obligated to purchase is not greater than the number of shares that they may purchase by exercising their option to purchase additional shares. In a naked short position, the number of shares involved is greater than the number of shares in their option to purchase additional shares. The underwriter may close out any short position by either exercising their option to purchase additional shares or purchasing shares in the open market.

●	Stabilizing transactions permit bids to purchase the underlying security as long as the stabilizing bids do not exceed a specific maximum price.

●

Syndicate covering transactions involve purchases of our shares of common stock in the open market after the distribution has been completed to cover syndicate short positions. In determining the source of shares to close out the short position, the underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the underwriter's option to purchase additional shares. If the underwriter sells more shares than could be covered by the underwriter's option to purchase additional shares, thereby creating a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

●	Penalty bids permit the representative to reclaim a selling concession from a syndicate member when the shares of common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

●	In passive market making, market makers in our common stock who are underwriters or prospective underwriters may, subject to limitations, make bids for or purchase our common stock until the time, if any, at which a stabilizing bid is made.

These activities may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result of these activities, the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on NASDAQ or otherwise and, if commenced, may be discontinued at any time.

Neither we nor the Underwriter makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor the underwriter makes any representation that Aegis will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

Listing

Our common stock is listed on The Nasdaq Capital Market under the trading symbol "CYN." We do not plan to list the Pre-funded Warrants on the Nasdaq Capital Market or any other securities exchange or trading market.

Lock-Up Agreements

Pursuant to "lock-up" agreements, our executive officers and directors have agreed, subject to limited exceptions, not to directly or indirectly offer to sell, sell, pledge or otherwise transfer or dispose of any of shares of (or enter into any transaction or device that is designed to, or could be expected to, result in the transfer or disposition by any person at any time in the future of) our common stock, enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of our common stock, make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of common stock or securities convertible into or exercisable or exchangeable for common stock or any of our other securities or publicly disclose the intention to do any of the foregoing, subject to customary exceptions, for a period of ninety (90) days from the closing date of this offering. The lock-up shall not apply to transactions under any Rule 10b5-1 sales plan or transactions under or modifications to any Rule 10b5-1 sales plan by the Company's officers and directors.

Securities Issuance Standstill

In addition, we have agreed that for a period of thirty (30) days from the closing date of the offering, without the prior written consent of the Underwriter, we will not (a) offer, sell, issue, or otherwise transfer or dispose of, directly or indirectly, any equity of the Company or any securities convertible into or exercisable or exchangeable for equity of the Company; (b) file or caused to be filed any registration statement with the Securities and Exchange Commission relating to the offering of any equity of the Company or any securities convertible into or exercisable or exchangeable for equity of the Company; or (c) enter into any agreement or announce the intention to effect any of the actions described in subsections (a) or (b) hereof.

Discretionary Accounts

The Underwriter does not intend to confirm sales of the securities offered hereby to any accounts over which it has discretionary authority.

Passive Market Making

In connection with this offering, the Underwriter may engage in passive market making transactions in our common stock on the Nasdaq Stock Market in accordance with Rule 103 of Regulation M promulgated under the Exchange Act during a period before the commencement of offers or sales of shares of our common stock and extending through the completion of the distribution.

Indemnification

We have agreed to indemnify the Underwriter against certain liabilities, including liabilities under the Securities Act, and liabilities arising from breaches of representations and warranties contained in the underwriting agreement, or to contribute to payments that the Underwriter may be required to make in respect of those liabilities.

Other Activities and Relationships

The Underwriter and certain of its affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities.

If the Underwriter or its affiliates have a lending relationship with us, they routinely hedge their credit exposure to us consistent with their customary risk management policies. The Underwriter and its affiliates may hedge such exposure by entering into transactions that consist of either the purchase of credit default swaps or the creation of short positions in our securities or the securities of our affiliates, including potentially the common stock offered hereby. Any such short positions could adversely affect future trading prices of the common stock offered hereby. The Underwriter and certain of its affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.
