Electrochemical biosensors for SARS-CoV-2 detection: Voltametric or impedimetric transduction?

Bioelectrochemistry. 2022 Oct:147:108190. doi: 10.1016/j.bioelechem.2022.108190. Epub 2022 Jun 11.

Abstract

During the COVID-19 pandemic, electrochemical biosensors have shown several advantages including accuracy, low cost, possibility of miniaturization and portability, which make them an interesting testing method for rapid point-of-care (POC) detection of SARS-CoV-2 infection, allowing the detection of both viral RNA and viral antigens. Herein, we reviewed advancements in electrochemical biosensing platforms towards the detection of SARS-CoV-2 based on voltametric and impedimetric transduction modes, highlighting the advantages and drawbacks of the two methods.

Keywords: Aptasensor; DNA-sensor; Immunosensor; Impedimetric biosensor; MIP-sensor; SARS-CoV-2; Voltametric biosensor.
