Carbon nanomaterials have piqued the interest of medicinal researchers due to their exceptional characteristics and flexible dimensional configurations. Carbon Nanomaterials (CNMs) exhibit electrical characteristics, a large thermal surface area, and a high cellular internalisation, making them ideal for medication and gene delivery, antioxidants, bioimaging, biosensing, and tissue engineering. Carbon nanomaterials such as graphene, carbon nanotubes, fullerenes, nanodiamond, quantum dots, and many more will have exciting uses in the future. The functionalization of the carbon nanomaterial surface has the potential to change its chemical and physical characteristics, as well as increase drug loading capacity, biocompatibility, reduce immune response, and direct drug delivery to the desired spot. Carbon nanoparticles might possibly be used with proteins and pharmaceuticals to minimise toxicity and improve efficacy in the pharmaceutical industry. Carbon nanomaterials are so ideal for use in pharmacological or biological systems.
