The COVID-19 outbreak led to an uncontrollable situation and was later declared a global ***-PCR is one of the reliable methods for the detection of COVID-19,but it requires transporting samples to sophisticated laboratories and takes a significant amount of time to amplify the viral ***,there is an urgent need for a large-scale,rapid,specific,and portable detection *** nanomaterials-based detection technology has been developed and it showed advancement over the conventional methods in selectivity and *** review aims at summarising some of the most promising nanomaterial-based sensing technologies for detecting *** possess unique physical,chemical,electrical and optical properties,which can be exploited for the application in ***,nanomaterials work on the same scale as biological processes and can be easily functionalized with substrates of *** devices do not require extraordinary sophistication and are suitable for use by common individuals without high-tech *** and colorimetric methods similar to glucometer and pregnancy test kits are discussed and reviewed as potential diagnostic devices for *** devices working on the principle of immune response and microarrays are also discussed as possible *** such as metal nanoparticles,graphene,quantum dots,and CNTs enhance the limit of detection and accuracy of the biosensors to give spontaneous *** challenges of industrial-scale production of these devices are also *** mass production is successfully developed,these sensors can ramp up the testing to provide the accurate number of people aff ected by the virus,which is extremely critical in today’s scenario.
