Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have developed a technique for embedding nanoscale photonic crystals into the glass face of a watch so that when it is exposed to UV light, the design made by the crystals becomes visible. The team at Nanoga, a new startup that has been spun off to market this research, believes that this technology can be used to offer luxury watch makers an anti-counterfeiting method that is quick and easy to adopt.

Scientists putting a modern spin on a 50-year-old idea have created a hologram that could make for better smart glasses and improved anti-counterfeiting measures.

The young Czech company IQ Structures s.r.o. from the town of Řež near Prague, in collaboration with the Institute of Physics of the Czech Academy of Sciences and Vietnamese partners, is preparing a revolutionary innovation in the field of nanotechnology. This allows, for example, the production of much higher quality security protection elements against counterfeiting money or documents, as well as application surfaces for the production of hydrogen from water.
