Item 8.01

Other Events

As previously disclosed in a Form 8-K filed by Nanogen, Inc. (the “Company”) on May 23, 2008, the Company is not in compliance with the $1.00 minimum bid price requirement for continuing listing on NASDAQ. On October 16, 2008, NASDAQ Stock Market filed an immediately effective rule change to suspend temporarily the enforcement of its $1.00 minimum bid price requirement for listed companies through Friday, January 16, 2009. As a result of this rule change, the Company was informed by NASDAQ that it had until February 26, 2009 to regain compliance of the minimum bid price requirement (see the Company’s Form 8-K filed on October 27, 2008). On December 19, 2008, NASDAQ extended the temporary suspension of minimum bid price requirement until April 20, 2009, on which date the rules will be reinstated. As a result of this extension, on February 12, 2009 NASDAQ informed the Company that the Company will now have until May 27, 2009 to regain compliance of the minimum bid price requirement. The Company can regain compliance, either during the suspension or during the compliance period resuming after the suspension, by achieving a $1.00 closing bid price for a minimum of 10 consecutive trading days.
