Exhibit 99.2

To:      The Board of Directors
         Applied DNA Sciences, Inc.

This letter is to serve as official  notice of my resignation as Chief Operating
Officer and Chief  Financial  Officer of Applied DNA  Sciences,  Inc.  effective
October 19, 2005.  Due to family  circumstances  and the  company's  decision to
relocate to New York, I am unable to continue on in my role with the company.

In order to ensure a smooth transition,  I will be available to the company on a
consulting basis until such time as my services are no longer needed.

Sincerely,

/s/ KARIM KLEMM
