Multicolored Nanocolloidal Hydrogel Inks For Anti-Counterfeiting


Abstract "Nanocolloidal gels are emerging as a promising class of materials with applications as inks in 2D and 3D printing. Polymer nanoparticles (NPs) offer many advantages as potential building blocks of nanocolloidal gels, due to the ability to control NP dimensions, charge, surface chemistry, and functionality; however, their applications as inks in printing are yet to be explored. Here, ... » read more

IC security using AFMs The National Institute of Standards and Technology (NIST) has developed a probe assisted doping technique (PAD), a technology that could help prevent counterfeit chips and electronic devices from entering the market. PAD involves creating a unique ID tag on every chip using an atomic force microscope (AFM). Basically, an AFM system incorporates a cantilever with a tin... » read more
