COVID-19 Biosensors

Researchers at the University of Waterloo have developed a COVID-19 biosensor.

They are using an electronic device utilizing a graphene-based thin-film covalently functionalized with antibodies for the detection of a COVID-19 SPIKE protein. This device was demonstrated to be able to detect COVID-19 within a few minutes at ultra-low concentrations.
