Applied DNA Sciences Develops DNA Petrochemical Marker

LOS ANGELES, March 10 -- Applied DNA Sciences Inc. (BULLETIN BOARD: APDN) a security solutions company focused on supply chain management relating to counterfeiting, fraud, piracy and product diversion, announced today the successful initial testing of their Encapsulated Botanical DNA (EBD) marker for the petrochemical industry. The testing involved the formulation of an economical concentration of the EBD marker that was introduced into gasoline and diesel fuel process systems. The EBD survived the harsh solvent chemical environment and was successfully extracted and authenticated.

The goal of the EBD petrochemical marker program is to meet the increased demand for the next generation petroleum marker for crude oil and commodity chemicals; gasoline, fuel oils, diesel, and agricultural chemicals. The program also includes the development of an EBD system for tracking and monitoring strategic reserves, in the U.S. and abroad.

The global problem of fuel adulteration, dilution, diversion, and misbranded fuel is substantial. BusinessWeek magazine, citing the World Customs Organization, reports that illegal fuel trade contributes to the $512 billion in lost revenue from counterfeiting. Peter Brocklesby, president of Applied DNA Sciences stated, "Estimates from information supplier Freedoina, suggests the US market for fuel additives is expected to exceed $8 billion by 2008. We believe that marker technologies, like our EBD may offer a significant potential solution in brand protection by creating an effective tool in supply chain management for product distribution."

Applied DNA Sciences has filed a patent application that not only covers the use of the novel EBD marker with petrochemicals, but describes the system and method for recovery, assay, and monitoring the concentration of the EBD marker in a piping/delivery system -- with Supervisory Control and Data Acquisition (SCADA) capability.

ADNAS will be working with the Department of Energy under a Cooperative Research and Development Agreement, to conduct the necessary feasibility, scaling and modeling efforts. In parallel, ADNAS will work to attract an industry partner for financial participation and deployment of the EBD marker solution.
