Protein biosensors show promise for SARS-CoV-2 testing – The Science Board
Scientists have developed biosensors to detect SARS-CoV-2 proteins and antibodies in simulated nasal fluids and human sera, according to a study published in Nature…
Biosensors are devices used to detect the presence or concentration of specific biomolecules or biological structures. In this case, the researchers designed protein-based biosensors that recognize specific molecules on the surface of a particular virus and bind to them, then emit light through a biochemical reaction.
The scientists applied this approach to design biosensors of antibodies against SARS-CoV-2 protein epitopes and of the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein.
