Detection of SARS-CoV-2 S1 protein using terahertz meta-biosensor

Abstract

The new type of coronavirus pneumonia (SARS-CoV-2) has caused the cumulative number of confirmed diagnoses worldwide to exceed 1.7 Billion, and it has led to heavy damage to all aspects of the world. Therefore, it is crucial to detect SARS-CoV-2 with high sensitivity, free-label, and rapid quantification. Here, a terahertz (THz) metamaterial (MM) biosensor was designed and has achieved a high-sensitivity and quantitative detection of trace SARS-CoV-2 S1 protein.
