Anti-namaak vingerafdrukken op nanoschaal

Counterfeiting is conducted in almost every industry, and the losses caused by it are growing as today's world trade continues to increase. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have demonstrated anti-counterfeit nanoscale fingerprints generated by randomly distributed nanowires.
They prepared silver nanowires coated with fluorescent dyes and cast them onto the surface of transparent PET film. The resulting non-repeatable patterns characterized by the random location of the nanowires and their fluorescent colors provide unique barcodes suitable for anti-counterfeit purposes. An article about the research is published in Nanotechnology.
