Subsequent Events	Management has evaluated events subsequent to June 30, 2013 through the date that the accompanying condensed consolidated financial statements were filed with the Securities and Exchange Commission for transactions and other events which may require adjustment of and/or disclosure in such financial statements. In July 2013, we invoiced DARPA for milestones 13 and 14 under our contract for a total of $404,362 and collected that amount. In July 2013, we borrowed $400,000 from two of our directors under 90 day notes bearing 10% interest (the “Notes”). If we do not pay back those loans by October 9, 2013, then the notes will bear interest at a penalty rate of 12% and the noteholders will have the right at their discretion (i) to convert their principal and accrued interest into shares of common stock at $0.088 per share (the “Conversion Price”) and (ii) receive warrants to purchase common stock equal to 50% of the principal converted under the Notes, with an exercise price of $0.132 per share. That potential conversion price and warrant exercise price were based on the same pricing mechanism that we have used in prior equity unit financings since March 2012 (see Note 6) which are based on 80% of the then current market price of our common stock and with the warrant exercise price based on 120% of the same then current market price. We have reserved 6,931,818 shares of common stock to support the conversion in full of the Notes and accrued interest as well as the exercise in full of the warrants (should such conversion and/or issuance occur). Subsequent to June 30, 2013, we issued 2,795,367 shares of restricted common stock to the holders of five notes issued by the Company in exchange for the partial conversion of principal and interest in an aggregate amount of $173,960 at an average conversion price of $0.06 per share. Subsequent to June 30, 2013, our compensation committee approved the issuance of four stock option grants to four of our executives. The options carried an exercise price of $0.10 per share, have a ten year life and vest over the following schedule: 25% on July 1, 2014, 25% on July 1, 2015, 25% on July 1, 2016 and 25% on July 1, 2017. The numbers of shares underlying each of the stock option grants were as follows: 2,000,000 shares to our chief executive officer and 500,000 shares each to our president, chief science officer and chief financial officer. Subsequent to June 30, 2013, we invoiced Battelle for $20,340 under our subcontract. In July 2013, we issued 514,453 shares of common stock pursuant to our S-8 registration statement covering our Amended 2010 Stock Plan at an average price of $0.11 per share in payment for legal and internal controls services valued at $54,256 based on the value of the services provided. In August 2013, we completed a unit subscription agreement with four accredited investors (the “Purchasers”) pursuant to which the Purchasers purchased $100,000 of units (the "Units" and each a "Unit"), with each Unit consisting of (i) one share of Common Stock at a price per share of $0.111 and (ii) a warrant to purchase such number of shares of Common Stock as shall equal (a) fifty percent of the Subscription Amount divided by (b) $0.111 (the "Warrant Shares") at an exercise price of $0.167 per Warrant Share. This resulted in the issuance of 900,901 shares of Common Stock and 450,451 Warrant Shares. In August 2013, 13 warrant holders exercised 6,274,394 warrants to receive 3,248,601 shares in cashless transactions.
