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. 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. These new sensors, built using the same fabrication processes that are commonly used for silicon computer chips, are small and accurate with capability to detect multiple gases at the same time. N5 is working to develop arrays of multi-analyte sensors on a single chip, which can be integrated with smart phones, allowing industrial workers, first-responders, and soldiers to assess the dangers of their surroundings rapidly and accurately in real-time using their smart phones.
