‘Liquid fingerprinting’ technique instantly identifies unknown liquids

A new company will commercialize sensing technology that can perform instant, in-field characterization of the chemical make-up and material properties of unknown liquids. Validere aims to develop the licensed technology, called Watermark Ink (W-INK), into a pocket-sized device that could be used by first responders to quickly identify chemical spills, or by officials to verify the fuel grade of gasoline right at the pump.
