          APPLIED DNA SCIENCES SIGNS BUSINESS DEVELOPMENT AND TRADEMARK
            LICENSE AGREEMENT WITH DR. SUWELACK SKIN & HEALTHCARE AG

STONY BROOK, N.Y., May 9 /PRNewswire First Call / -- Applied DNA Sciences, Inc.
(OTC BB: APDN), a DNA security solutions company, announced that it signed an
agreement with Dr. Suwelack Skin & Healthcare AG ("Suwelack") providing Suwelack
rights to use APDN's SigNature(TM) logo, which is printed with ink containing
our proprietary encrypted botanical DNA technology, and to participate in its
SigNature(TM) Program. The terms of this one year license agreement provide
Suwelack with a limited, non-exclusive, non-transferable right to use the
SigNature(TM) logo on its packaging and labels.

Created by APDN, the goal of the SigNature(TM) Program is to provide a secure,
cost effective and forensic method to help companies like Suwelack protect their
intellectual property assets and the value of their brand. This program is based
on APDN's proprietary platform technology whereby nanoscopic botanical DNA is
embedded in a proprietary protective coating that withstands commercial
processing and gives DNA a life of several hundred years. Botanical DNA will be
embedded into the ink that will be used in the SigNature(TM) logo utilizing both
overt and covert DNA security technologies. This botanical DNA can later be
sequenced and decoded from the SigNature(TM) logo to verify the authenticity of
Suwelack's products.

Suwelack is recognized in Germany as the leader in the innovation, development
and manufacture of biomatrices for cosmeceutical and healthcare applications.
Suwelack has adopted the SigNature(TM) Program as one of many new initiatives
that complement its expansion into the North American market.

According to Nikolaus Uleer,  Chief Executive Officer of Suwelack,  "We are very
pleased to utilize DNA  encryption  technology in our  packaging.  It provides a
secure, forensic, and most importantly, cost effective approach, that we believe
will provide a positive contribution to the development of our brand."

The SigNature(TM) Program is the first initiative by APDN to introduce to the
market a range of ready-to-use security solutions aimed at brand protection and
authentication, and addressing the global need to combat counterfeit and piracy.

Dr. Benjamin Liang, Chief Scientist of Applied DNA Sciences, said "We believe
that our technology provides an immediate benefit and relevance to a company
like Suwelack that has applications in both skincare and healthcare. From a
business development perspective, we can deliver a fast-track security solution
intended to provide both strategic and tactical value to our clients. We are
pleased that Suwelack is our first commercial partner in Europe."
