The spike protein of SARS-CoV-2 can be detected by electrochemical impedance spectroscopy using antibody desorption from iron magnetic nanoparticles
Description
SARS-CoV-2 is a matter of concern. Here, biosensors were prepared using iron magnetic nanoparticles containing antibodies against the receptor binding domain (RBD) of the spike protein. Antibodies were adsorbed to nanoparticles in three
