A starch and graphene hydrogel geared towards electrodes for brain implants is developed

The Materials + Technology research group at the UPV/EHU's Faculty of Engineering -- Gipuzkoa has, in collaboration with the University of Strasbourg, developed some hydrogels with potential biomedical applications. Starch was used as the raw material and a three-dimensional network structure was produced. When graphene and salvia extracts were added, the hydrogel was provided with electrical properties as well as the necessary antibacterial ones.
