The Role Of Biosensors In Detection Of SARS-Cov-2: State-Of-The-Art And Future Prospects

The world is fighting a pandemic so grave that perhaps it has never been witnessed before; COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). As of August 31st, 2022, the WHO declared the total number of confirmed cases was 599,825,400, with 6,469,458 confirmed deaths from 223 countries under the scourge of this deadly virus. The SARS-CoV-2 is a β-coronavirus, which is an enveloped non-segmented positive-sense RNA virus. It is a close relative of the SARS and MERS viruses and has probably entered humans through bats. Human-to-human transmission is very rapid. People in contact with the patient or even the carriers became infected, leading to a widespread chain of contamination. We are presenting a mini-review on the role of biosensors in detecting SARS-CoV-2. Biosensors have been used for a very long time for viral detection and can be utilized for the prompt detection of the novel coronavirus. This article aims to provide a mini-review on the application of biosensors for the detection of the novel coronavirus with a focus on cost-effective paper-based sensors, nanobiosensors, Field effect transistors (FETs), and lab-on-chip integrated platforms.
