Schematic schema for the stages of screening and specific detection of COVID-19 based on electrochemical biosensor. (A) Immobilization of MV-gal1 on the SCPE-GNP. (B) Dropping the SARS-CoV-2 on the MV-gal1-SCPE-GNP to screening the spiked COVID-19. (C) Dropping the Au/Anti-SARS-CoV-2 spike On the MV-gal1@SARS-CoV-2 Antigen to specific detection of COVID-19.
