Role of Graphene and Graphene Oxide Applications as Optical Biosensors in Pandemic

Abstract

In recent pandemic period it becomes very important to provide a detection technique which will offer high sensitivity, selectivity with low limit of detection. Optical biosensors provide an intriguing path for continuous and rapid detection of target analyte in order to enhance health outcomes. In these recent years nanomaterials have been largely focused in order to design highly efficient biosensors. As Noble metal nanoparticles are well known for their unique properties like plasmonic property, superconductivity and biocompatibility, were extensively used in different scientific field. Noble metal like gold, silver and platinum nanoparticles are used in designing different biosensors. These biosensors were widely used in virus detection of different respiratory related health problems like COVID-19. In this mini review we addressed the optical biosensors fabricated by using noble metal nanomaterials which are used in rapid detection with highly sensitive and selective detection methods with low Limit of detection in recent pandemic period.
