Smart facemask detects SARS-CoV-2

Nanoengineers at the University of California at San Diego have created a N95 mask with a sensor that detects SARS particles in exhaled breath.  “The sensor, which is in the process of being perfected, consists of a strip similar to a pregnancy test with small blister pack compartment. The strip’s surface would collect particles from exhaled breath. Once a test is desired, the user simply squeezes on the blister pack, which mixes special nanoparticles with the proteases that may exist on the strip’s surface. If they do, the color changes, indicating the presence of the proteases and therefore the virus.”  MORE
