SG Penn :: International Society for Optical Engineering :: 22 January 2004 :: ISBN 0819452130
Nanobarcodes particles from Nanoplex Technology, CA, USA, are claimed to be virtually impossible to counterfeit and are cylindrically shaped, striped metal particles. Readout is based on differential reflectivity using an optical microscope plus software for automated particle decoding. An unlimited number of unique codes are available for multiplexing, while combinations of codes offer even higher multiplexing. Nanobarcodes have unparalleled materials compatibility and offer automated, scaleable manufacture. They are ideal for documents and product security applications, offering unlimited number of unique codes. Nanobarcode particle technology is compatible both on and within a number of host mediums, including inks, explosives, paints, varnish, paper and plastics. (2 fig, 4 ref)
