No More Counterfeiting – Thanks to Photon Crystals from ITMO
Scientists from ITMO University have suggested a novel production method for anti-forgery protection tags that is cheaper and quicker than its analogs. The new method uses magnet-sensitive photon crystals for ink jet printing. The resulting tags are liquid systems with magnetic particles inside a solid shell; in response to a magnet, the particles assemble into a specific colored pattern. According to its authors, the new method will be more reliable than its counterparts. The study is described in a paper published in Advanced Optical Materials.

ITMO Physicists Create Unclonable Anti-Counterfeiting Silicon Labels
Scientists from ITMO University developed unclonable anti-counterfeiting labels, which are based on silicon nanoparticles modified with a laser. It’s impossible to change the color, structure, and location of the particles: these parameters are random, which makes the label safe from counterfeiting. In order to check if it’s authentic, all you need to do is upload its picture into a special program.
