Applied DNA Sciences Gains Exclusive North American Rights to Distribute Intruder Spray Systems

STONY BROOK, NY--(Marketwire - May 17, 2011) - Applied DNA Sciences, Inc. (OTCBB: APDN), a provider of DNA-based anti-counterfeiting technology and product authentication solutions, announces that it has signed an agreement with RedWeb Technologies giving the company exclusive rights in North America to distribute the Sentry 500 Intruder Spray Systems embedded with SigNature DNA. This system is already being used in Sweden with great success (APDN Press Release May 5, 2011).

APDN believes that the market for this product in North America is vast and as yet untapped. For instance, in jewelry stores alone, the sales potential is upwards of $32 million for initial installation with the potential for renewal fees every 18 months.

Multiple spray heads can be fitted at the entry points of premises and on activation emit a burst of DNA solution onto the offenders. The solution contains a rapid-read tracer and a unique DNA code, linking the criminals irrefutably to the crime scene. The DNA Spray can be armed by a panic button and/or linked to an existing intruder alarm system. As the DNA fear factor amongst criminals is high, it is likely that sprayed intruders will flee the crime scene before stealing any goods. Police often know who the thieves are, but don't have evidence to convict them or link them to the crime. DNA is the link.

''Criminals will always find the path of least resistance to their attack. The SmartDNA™ system provides an effective deterrent to crime which means the criminals will move away to easier targets ensuring the bank can continue to offer banking services to its customers in an ever competitive market place," commented Chris Taylor, Managing Director of RedWeb Technologies.

Premises protected with SmartDNA immediately become hardened targets as criminals are wary of DNA technology -- they know that DNA links them to crimes they commit. The DNA Spray can be used by retail outlets, schools, jewelers, gas stations, even major International banks, to protect their valuable stock and assets.

"SmartDNA both deters thieves breaking in to properties and assists in the recovery of stolen goods so that they can be returned to their rightful owners. The system is easy to use and inexpensive compared to the possible cost of a robbery. Our Spray Systems are being used throughout Europe with great success and we are excited to have our products, combined with SigNature DNA, distributed by APDN in North America," commented Chris Smith, Group Sales Director of RedWeb Technologies.

Traces of the DNA solution can be taken from the skin, hair and clothing of offenders, and sent to APDN for forensic analysis to prove that the offender has broken into a particular premises. Although invisible and harmless, the SmartDNA marker will remain on an offender for weeks -- clinging to fibers and sitting in creases of the skin.
