DNA ink

The DNA ink is complied of two components:- The first is a anti-counterfeit ink, which can be authenticated by laboratory DNA analysis- The second is a proprietary technique that allows for on-site, real time authentication, using the instant detection feature of the DNA Ink. This instant verification process has been designed to quickly allow sampling at any point in the product supply chain. By applying a specifically matched testing buffer fluid with the testing pen (pictured at right) across an authentic DNA Ink surface, a biochemical reaction occurs between the coating of the DNA ink molecules in the ink and the buffer fluid. This reaction manifests as a reversible color change, with the ink changing color from blue to pink, and back to blue within seconds. The instant detection test is repeatable up to 50 times.
