N5 Sensors, a University of Maryland spin-off founded by UMD Research Scientist Abhishek Motayed, is commercializing a new generation of chip-scale chemical sensors 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 the 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.
