Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1. Business and Organization Outlook The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of our business. As reflected in the accompanying consolidated financial statements, we had a net loss of $5,796,831, and cash used in operations of $2,799,096, for the nine-months ended September 30, 2016, and at September 30, 2016, we had working capital of $1,041,864, current assets of $1,873,107, and an accumulated stockholders’ deficit of $89,680,852. The foregoing factors raise substantial doubt about our ability to continue as a going concern. Ultimately, our ability to continue as a going concern is dependent upon our ability to attract significant new sources of capital, attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our technologies. The consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern. We have been, and anticipate that we will continue to be, limited in terms of our capital resources. Our total cash balance was $1,731,946 at September 30, 2016. We had revenues of $215,249 in the nine-months ended September 30, 2016, which amount was not sufficient to fund our operations. We generally have not had enough cash or sources of capital to pay our accounts payable and expenses as they arise, and have relied on the issuance of stock options and common stock, as well as extended payment terms with our vendors, to continue to operate. We will be required to raise substantial additional capital to expand our operations, including without limitation, hiring additional personnel, additional scientific and third-party testing, costs associated with obtaining regulatory approvals and filing additional patent applications to protect our intellectual property, and possible strategic acquisitions or alliances, as well as to meet our liabilities as they become due for the next 12 months. As of September 30, 2016, we had $5,447,876 in principal amounts due on various debt obligations (see Note 4). Of that amount, $4,834,305 is due on notes convertible into shares of our common stock at our option on their maturity dates on June 1, 2018, $283,571 is convertible into shares of our common stock at our option on their maturity dates on September 17, 2019, and $280,000, maturing July 8, 2017, is convertible by the holder at any time. We also had $50,000 principal amount outstanding due on a line of credit that is payable December 1, 2017. Interest continues to accrue on each of these notes. Additionally, we had $290,076 of accounts payable and accrued expenses (see Note 7). The unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to Rule 8-03 of Regulation S-X under the Securities Act of 1933, as amended. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for annual financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. These unaudited consolidated financial statements and notes should be read in conjunction with the Company’s audited financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2015 filed with the Securities and Exchange Commission (the “SEC”) on March 30, 2016.

Outlook

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of our business.
