 We explain how graphene could be used in biomedical applications to improve people's lives. This is Stan. Stan is blind, but he hopes to be able to take part in a clinical study using graphene devices that could help his eyesight go from pitch black to perceiving shades and shapes. How is this possible? Graphene has the ability to electrically stimulate the nervous system of the brain. There, it could record the electrical activity of the nerves and inject charge into the optical nerve and produce an image from an external camera. But Stan is not the only patient that could benefit from graphene's attributes. His best friend Anna has epilepsy. Anna is following recent studies that show how graphene could be placed into a delicate sensor able to detect the specific areas in the brain that are responsible for the seizures. That way, clinicians could understand where exactly in the brain the episode is happening and how it can be predicted or even cured. During her research, Anna met Sophia, a scientist. She explained one of the key advantages of graphene devices. Their multifunctionality can both record and stimulate the electrical activity of the brain as well as locally release therapeutications on demand that could offer multiple treatment options. That's also how the doctors hope to be able to help Sophia with the effects of Parkinson's disease. This new generation of thin and flexible graphene-based devices could minimize shaking, tremor, and other motor symptoms. While the graphene flagship scientists focus mainly on blindness, epilepsy, and Parkinson's disease, research in the use of graphene and 2D materials in medicine is expanding globally. Some other biomedical applications currently under development include cancer treatment, tissue engineering, and drug delivery. In addition, graphene's thinness, flexibility, and excellent sensing capabilities makes it suitable for use in wearables, providing STAN, Anna and Sophia basic health checks that they can monitor themselves and use to inform their doctors. Although research on graphene for medicine is still at its early stages, tests show promising results that could offer medical professionals new, multifunctional, and more precise capabilities and help improve the quality of life for millions of patients worldwide.
