Abstract

Lab on a chip (LOC) device intakes fluid and makes it flow through the microchannels, to achieve rapid, highly sensitive and low-cost analysis with significant yield. Graphene has vast potential to be used in LOC devices owing to its remarkable and unique properties. A trustworthy, swift, inexpensive and facile detection scheme is of urgency due to the current situation of COVID-19 to break the chain of transmission and lab-on-chip based biosensor has materialized itself as a realistic solution for this purpose. The addition of Graphene has augmented the sensing capability of the LOC devices to a superior level. Recently, Graphene-based lab-on-chip type biosensor is effectively used for faithful detection of SARS-CoV-2 and this draws the attention of the researchers to review the recent progress in Graphene-based LOC platforms for detection of viruses and the same has been reviewed here.
