A Review on Biosensors for COVID-19

Abstract

The global spread of the severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) has altered people’s lives and had a significant influence on economies and communities. It has created an insatiable demand for advanced diagnostic tools for rapid and accurate diagnosis, investigations, and quarantine techniques, particularly because vaccine or therapies are unavailable. Presently, quantitative real-time polymerase chain reaction (qRT-PCR) is commonly utilised for detecting corona virus disease 2019 (COVID-19), however this method is time-consuming, labor-intensive, and may not be quickly deployable in remote or resourceconstrained situations. This could make it more difficult to obtain reliable statistics on SARS-CoV-2 infection rates and communal spread in the populace. This paper covers the present state of diagnostic approaches, their drawbacks, and the use of biosensors for SARS-CoV-2 diagnosis. Electrochemical biosensors, optical biosensors, and surface plasmon resonance are examples of emerging biosensing devices being employed for the detection of ribonucleic acid (RNA) viruses. They might be useful instruments for a faster, more accurate, mobile, and more hopeful diagnosis in the present epidemic.This paper also discusses current problems and recommendations for developing robust biosensors for the efficient, affordable, and precise detection and monitoring of COVID-19.
