Real-time Sensing of Trace Biomarkers from Viruses with a Microfluidic Immunosensor: A Case Study of SARS-CoV-2 Detection in Cold-chain Food

Abstract

<div>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. <br></div>
