The pandemic caused by the SARS-CoV-2 virus disrupted global operations and societal living while claiming the lives of millions across the globe. The ability to detect SARS-CoV-2 during the early stages was crucial in combatting the virus. Although antigen tests have proven to be an invaluable tool for rapid testing of SARS-CoV-2 infections, this method is limited in scope and is unable to provide fingerprint identification of the spike protein, which is necessary to identify variants of the virus.
The team of researchers in the study “Towards Label-free detection of viral disease agents through their cell surface proteins: Rapid screening SARS-CoV-2 in biological specimens” by Nihal, et al., present a highly specific biosensing method using surface-enhanced Raman scattering (SERS) to detect the cysteine residues of the SARS-CoV-2 spike protein subunit, S1 protein. The researchers were able to consistently detect the cysteine residues in human blood plasma, mucus and saliva samples spiked with the S1 protein using their label-free SERS method.
