Silicon Valley-based holographic security firm Holoptica has had a patent related to synthetic DNA published for its holoQR product.The solution involves a security diffractive code of quick response using synthetic DNA and nanoparticles of highly variable properties, writes the company's patent.The substance is formed by a metalized foil with an imprinted code of quick response, which is further covered by an imprinted layer of synthetic DNA and another imprinted layer of synthetic nanoparticles.An imprinted layer of synthetic DNA and the imprinted layer of synthetic nanoparticles are covered by a top layer consisting of a protective transparent foil.For authentication, a reader is turned towards the imprinted layer of synthetic DNA and the imprinted layer of synthetic nanoparticles.The reader is connected via the Internet to a databank comprising registered information codes and variable properties coming from the imprinted layer of synthetic nanoparticles and from the imprinted layer of synthetic DNA.
