Subsequent Events [Abstract]
Subsequent Events	16. Subsequent Events We have evaluated events after the balance sheet date of December 31, 2012 and up to the date we filed this report. Subsequent to the year ended December 31, 2012, under the terms of the December 2012 underwriting agreement with Lazard Capital Markets, LLC (underwriter), the underwriter exercised the option to purchase an additional 1,053,000 shares and as a result we sold 1,053,000 shares on January 14, 2013, raising approximately $3,001,000 in gross proceeds before deducting underwriting discounts and commissions and other offering expenses payable by us. In February 2013, we entered into a mutual termination and release agreement with Senko, which terminated the Distribution Agreement with Senko, and all Senko rights, licenses and privileges granted under the distribution agreement terminated and reverted to the Company.  As a result of this termination agreement, we are obligated to pay Senko $1,200,000 in six quarterly installment payments of $200,000 each through May 2014.
