Graphene Transistors for Bioelectronics: Graphene Transistor Arrays for Recording Action Potentials from Electrogenic Cells (Adv. Mater. 43/2011)

A living cell is cultured on top of a graphene solution-gated field effect transistor (FET) and the cell action potential is detected with the transistor. As reported by Jose A. Garrido and co-workers on page 5045, arrays of graphene solution-gated FETs can be successfully used to record the electrical activity of living cells, demonstrating superior per-formance for bioelectronic applications.
