Abstract:
Detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV CoV-2) pathogen and protein biomarkers can improve the diagnosis accuracy for Coronavirus disease 2019 (COVID-19). Electrochemical biosensors have attracted extensive attention in the scientific community because of their simple design, fast response, good portability, high sensitivity and high selectivity. In this review, we summarized the progress in the electrochemical detection of COVID-19 pathogen and SARS-CoV-2 biomarkers, including SARS-CoV-2 spike protein and nucleocapsid protein and their antibodies.
