Multiplexed electrochemical sensor platform enables simultaneous detection of SARS-CoV-2 RNA and host antibodies

Scientists from the UK and USA have developed an antifouling nanocomposite-coated multiplexed electrochemical sensor platform that can simultaneously detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA and virus-specific antibodies. The platform has shown 100% accuracy in detecting viral RNA and IgG-specific anti-SARS-CoV-2 antibodies. The study is currently available on the medRxiv* preprint server.
