Bilayer graphene, transferred as a layer onto biopolymers, is used as a flexible biological interface material for electrical cell stimulation. Bilayer graphene provides a conductive layer without changing the cytocompatibility of the underlying layer, allowing electrical stimulation of cells on substrates of chosen composition. The production of flexible, biocompatible electrodes is described and the differentiation of neural cells is demonstrated for the first time from a graphene-based electrode.
