Futuristic Advancements in Biomass-Derived Graphene Nanoassemblies: Versatile Biosensors for Point-of-Care Devices

摘要

Graphene and its derivatives, graphene oxide (GO), and reduced graphene oxide (rGO) have gained a lot of interest in the field of biosensing applicationes due to their unique physicochemical properties. In recent days graphene derived from biomass waste has been undergoing a lot of development because it is stable, and has a structure with rich in carbon content, renewable and economically viable. In a way, it helps μs in waste management and resource recovery. There are different ways to synthesize graphene and its derivatives through pyrolysis, chemical vapour deposition (CVD), and carbonization etc. In different types of sensors like electrochemical sensors, fluorescent sensors, surface plasmon resonance (SPR) sensors, and surface-enhanced Raman scattering (SERS) sensors for detecting bacterial and viral pathogens, which can be designed from biomass derived graphene-based nanostructures. These types of sensors can be used in Point of care (POC) and wearable devices, which are now witnessing a great deal of development. It helps μs to carry on and analyze therapeutic and diagnoses for a disease from the comfort of our home which will be achieved soon.
