Researchers from the Juelich Research Center and the Technische Universitaet Muenchen developed a graphene-based transistor array that can record electrical signals generated by biological cells.
The team demonstrated an array of 16 graphene solution-gated field-effect transistors (G-SGFETs) - produced over a copper foil using standard photolithographic and etching and chemical vapor deposition processes. A biological cell layer analogous to the heart muscle was deposited directly over this array. The transistor array detected and recorded single cells' action potentials at high resolution.
