• 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.
