Scientists developing color-changing test strip to stick on face masks and detect COVID-19
Credit: UC San Diego SAN DIEGO - Researchers at the University of California San Diego are creating a test that could quickly detect COVID-19 using droplets from a person’s face mask.The strip attaches to a face mask as a sticker and then collects droplets from the person’s breath, changing color depending on results. Researchers said it’s very similar to a home pregnancy test. "Think of this as a surveillance approach, similar to having a smoke detector in your house," Professor and Lead Principal Investigator Jesse Jokerst said.
