QR code containing machine readable DNA and nanoparticles

Abstract

A security code is provided having a diffractive holographic code of a quick response type, a data-matrix two-dimensional code or other bar code types, formed by a metalized foil with the code embossed thereon. The diffractive holographic code is covered by layers of synthetic DNA and nanoparticles of highly variable properties. The imprinted layer of synthetic DNA and the imprinted layer of synthetic nanoparticles, are covered by a top layer formed of a protective transparent foil.

Claims

A security code comprising: an embossed diffractive holographic bar code; and an imprinted layer of synthetic DNA and synthetic nanoparticles covering the holographic bar code; and top layer consisting of a protective transparent foil covering the layer of synthetic DNA and synthetic nanoparticles.

2. The security code of claim 1 wherein the bar code comprises a quick response (QR) code.

3. The security code of claim 1 wherein the synthetic nanoparticles have magneto-resistive properties.
