Therapeutic Voyage of Graphene-based Biosensor

The study of carbon-based materials and nanoparticles is currently an exciting field of study in the domain of material science. One of the most prominent of these materials is graphene, along with its related components graphene oxide and reduced graphene oxide. A single-layer, two-dimensional nanomaterial called graphene (GN) is employed in many different industries, such as electronics and biology. Graphene is a remarkable two-dimensional substance that has earned the title of "wonder material." Its remarkable electrical, optical, thermal, and mechanical qualities have attracted significant attention. Graphene's intriguing characteristics have led to its integration into numerous biosensing applications. Graphene possesses remarkable chemical, electrical, and physical qualities. The distinctive properties of graphene, particularly its electrical conductivity, large surface area, and significant electron mobility, are focusing more attention on applications in biomedicine that facilitate easier health monitoring. Biosensors with high sensitivity and precision can enhance patient care, and offer an opportunity for an early illness diagnosis and clinical pathogen identification. Additionally, a wide range of biological molecules, including glucose, hydrogen peroxide, cholesterol, dopamine, etc., can be detected using graphene-based biosensors. This study evaluates contemporary developments regarding graphene-based biosensors and their prospects and difficulties in this rapidly developing profession in the coming era. Graphene-based nanomaterials are appropriate to be employed in various biological and sensory contexts, including medicine and gene transfer, because of their unusual topologies and extraordinary properties. Graphene's outstanding characteristics enable biosensing applications to obtain the appropriate sensitivity, selectivity, and repeatability for a range of targets.
