Hopkins researchers say they’ve developed a better way to test for COVID, other viruses

Imagine being able to swab the inside of your mouth, place it in a device and quickly know whether you’re infected with COVID-19. Johns Hopkins University researchers say they have developed a simple sensor that could quickly and accurately detect the virus that causes COVID-19 in saliva. The sensor isn’t on the market yet, but soon could revolutionize testing, the researchers say. It could be stationed at the entrances of hospitals, airports and schools, and potentially be put into handheld and even wearable devices.
