TL;DR: It is shown that single-layer graphene increases neuronal firing by altering membrane-associated functions in cultured cells, and hypothesize that the graphene–ion interactions that are maximized when single- layer graphene is deposited on electrically insulating substrates are crucial to these effects.

TL;DR: In this paper, the authors demonstrate the fabrication of flexible arrays of Graphene SGFETs on polyimide, a biocompatible polymeric substrate, and demonstrate the recording of cell action potentials from cardiomyocyte-like cells.

TL;DR: In this work, both experimental data and a model are presented on the coupling between living cells and graphene solution-gated field-effect transistors, with a significant increase in the total ionic strength in the cleft and the model of the cell-transistor coupling is extended to include the effect of ion accumulation and ion sensitivity.

TL;DR: In this article, the authors compare GFETs fabricated on rigid (SiO2 /Si and sapphire) and flexible (polyimide) substrates, and show that GFET, fabricated on the polyimide, exhibit extremely large transconductance values, up to 11mS·V-1, and mobility over 1750cm2 ·V−1·s−1.
