G&T Microseal nanometer anti-counterfeit technology---- Microseal's micro-size particles are made from silicon material with nanometer etching technologies and act as anti-counterfeit label or invisible mark to protect brand and product. The custom made micro-size markers can be etched from simple pattern widely to any letterform. Such micro particles can be easily adhered to any surface of aimed item or label mixed with varies of glues to form unique fingerprint patterns. The size of the micro-markers can range from sub-millimeter to as small as a human blood cell(10-20micron in diameter) with extremely fine resolutions (up to 0.3micron).
