Applied DNA Sciences, Inc. Announces Development of an Anti-Counterfeit DNA Marker System for the Textile Industry.

Business Editors

LOS ANGELES--(BUSINESS WIRE)--March 5, 2003

Applied DNA Sciences, Inc. (OTCBB:APDN), a provider of proprietary embedded-DNA biotechnology solutions that protect corporate and government intellectual property from counterfeiting and fraud, announced today that it is developing an application of its patented embedded-DNA authentication technology for the textile industry.

Applied DNA is developing a cost-effective system to "mark" raw textile materials and finished goods. The DNA markers would identify both the country of origin as well as the specific factories where a garment and/or its components were produced. The DNA markers would also protect intellectual property, such as brands, designs, patterns, and trademarked products from counterfeiting and fraud.

Applied DNA's planned textile solution will cost-effectively insert DNA markers during the textile manufacturing process. Applied DNA believes the DNA markers will remain embedded in the fabric or yarn for more than 100 years. It is believed the DNA markers will be able to withstand extremely harsh textile processes including desizing, scouring, bleaching, mercerizing, etc. The origin of raw textile materials and finished goods can be verified using Applied DNA's proprietary DNA detection methods.

Being able to cost-effectively identify the country of origin of textile components is important to the U.S. Customs Service, which is responsible for enforcing the textile and apparel preference laws in the U.S. Substantial revenues are lost by apparel manufacturers and retailers as a result of illegally counterfeited textile goods. Illegal textile imports have not only caused tens of thousands of U.S. textile workers to lose their jobs, but have resulted in the loss of import tariffs and taxes for government agencies.

"We are extremely enthused about the prospect of introducing a DNA marker system for the textile industry. The development of such a system could play a significant role in the U.S. textile and worldwide anti-counterfeit and anti-fraud markets," said Larry Lee, president of Applied DNA Sciences, Inc. "To date we have announced various applications for our embedded-DNA biotechnology solutions, including a DNA anti-counterfeit chip, the first DNA-tagged label security system utilizing processed DNA with anti-counterfeit ink, and now a textile application. Our DNA solutions have generated enormous interest from international retailers, developers of security solutions, pharmaceutical and textile companies, nuclear industry safety experts, home entertainment providers, and petroleum chemical executives."
