A new test can find antibodies in just 10 minutes. It uses wearable sensors that do not need a blood sample. These sensors can detect infections, such as COVID-19, with high sensitivity.
Professor Alexander Star from the University of Pittsburgh helps develop these sensors. They can also monitor how well vaccines work in people.
The sensors work in the interstitial fluid, which surrounds skin cells. This is helpful because it avoids traditional blood tests that take longer.
