Microfluidic Smartphone Dongle Detects COVID-19

Researchers at Rice University have developed a microfluidic device that can test for the presence of SARS-CoV-2 in a drop of blood and display its results once plugged into a cell phone. The test runs in under an hour, and works by detecting SARS-CoV-2 nucleocapsid protein using antibody-studded magnetic nanobeads. In tests, the device could detect very low levels of the protein, suggesting that it could function as a sensitive diagnostic tool. Read More
