Biomedical Applications of Graphene

Graphene is a versatile two-dimensional nanomaterial thanks to its unique physical and chemical characteristics. It has shown great potentials in different fields and revealed to be promising in biomedical research. The application of nanotechnology to health care through nanomedicine devices is revolutionizing medical approaches, imaging, and treatment. Numerous experimental studies have also been made to employ graphene as a vehicle for antitumoral therapies. Patients affected by brain tumor can greatly benefit from it. However, graphene remains an experimental material, and its in vitro and in vivo toxicity has been so far tested with controversial results. We will describe the chemical and physical properties of graphene, its main current uses in different fields, focusing on its putative role in neuro-oncology, and its possible long-term toxicity.
