N5 Sensors, Inc. of Rockville, MD is a University of Maryland spin-off leveraging innovations in nanoengineered materials and devices to create novel sensing and detection solutions. This new sensor technology can produce sensors whose selectivity can be precisely tuned to any small set of chemicals through the design of the nanocluster, something currently not possible with any other technology. N5 is currently commercializing a new-generation of chip-scale chemical sensor technology that can detect harmful chemicals mixed in air, such as industrial chemicals, automobile exhausts, cigarette smoke, and pollutants released from paints, cleaners, pesticides and other products. N5 is working to develop arrays of multi-analyte sensors on a single chip, which can be integrated with smart phones.
