A Real-Time, Selective, and Low-Cost Strategy for Detection of Trace Level Spike-Protein from SARS-CoV-2 with Application to Cold-Chain Food Quarantine


Utilizing an interdigitated microelectrode chip modified with an antibody probe, and integrating dielectrophoresis enrichment with interfacial capacitance sensing, a strategy is presented for detection of trace level spike-protein from SARS-CoV-2 on food.
