A point-of-care biosensor for rapid and ultra-sensitive detection of SARS-CoV-2.

In a recent study in Nature Biomedical Engineering, Wei's group constructed a field-effect transistor (FET) based on the "molecular electromechanical system" (MolEMS). MolEMS enabled FETs to specifically capture viral nucleic acids and efficiently transduce signals, achieving a rapid and ultra-sensitive detection of SARS-CoV-2.
