• 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 Researchers Develop Special Ink For Anti-Counterfeiting Protection

  Scientists from ITMO University, Bauman Moscow State Technical University, and the University of Toronto have developed a gel ink that emits light when exposed to monochromatic radiation of various wavelengths. This makes it possible to create complex images when applying tags to products – the scientists believe that the level of anti-counterfeiting protection offered by their invention is much higher than that of the existing counterparts. The research received support from a Russian Science Foundation and the Ministry of Science and Higher Education grant.
