Applied DNA Sciences – Technology for Anti-Counterfeit and Security

Earlier this month, I had some fun with a sign that I saw on Queensway in London, UK. It claimed that the neighborhood was safer because they were marking property with DNA. Perhaps they were referring to the SigNature Program from Applied DNA Sciences.

Applied DNA Sciences uses DNA markers from botanical sources. They rearrange the markers into unique encrypted sequences then embed the DNA onto consumer products that need to be protected, including drug tablets and capsules, banknote threads, holograms, artwork, and collectibles. The company claims that the markers embedded in indelible SigNature DNA ink is safe to consume.

There are varying levels of product verification:

• A SigNature DNA Encryption Pen can be used to detect the presence of their proprietary overt ink.
• An instant reader can be used to detect DNA.
• Portable PCR machines can produce “absolute authentication” in less than 30 minutes.
• Forensic-level, authenticated PCR.

PCR DNA amplification is performed using specific primers that can only be synthesized if the unique encrypted DNA sequence is known.

Applied DNA Sciences states that false positives occur in less than 1 in 1 trillion cases and can authenticate at levels acceptable for forensic use. The SigNature Program is effective against counterfeiting, product diversion, piracy, fraud and identity theft.
