Voltammetric Sensors: A Versatile Tool in COVID‐19 Diagnosis and Prognosis

Abstract

AbstractThe recent events of outbreaks of corona virus caused by the Severe Acute Respiratory Syndrome Coronavirus −2(SARS‐CoV‐2) raised a concern and increased urge for quick and rapid detection techniques of disease causing pathogens. The detection of the virus with high sensitivity and accuracy holds great importance. Nowadays, the most commonly employed technique is the Quantitative Reverse Transcription Polymerase Chain Reaction test (qRT‐PCR) and antigen test. While RT‐PCR technique is time consuming, expensive and labour intensive, antigen tests though simple, can often give false positive and false negatives. In this context, electrochemical biosensors developed in recent times have been identified as a potential strategy to overcome the limitations of these common techniques. This review article summarizes the current advancements in the field of voltammetric sensors for the detection of COVID‐19 virus and various biomarkers associated with it.
