EMBEDDED NANOPARTICLE ANTI-COUNTERFEIT PATTERNING ON A SUBSTRATE AND METHOD OF MAKING THE SAME

摘要

A method of coating a substrate with an anti-counterfeit pattern is provided. The method includes at least following steps: providing a substrate; depositing a first particles on the substrate to form a first predetermined pattern; and depositing a second particles that are nanoparticles on the substrate to form a second predetermined pattern. The second particles are different from the first particles and repulsively interact with the first particles.
