Wafer-scale fabrication of graphene-based field effect transistor arrays for extracellular measurements

摘要

The work is focused on the fabrication and analysis of graphene-based, solution-gated field effect transistor arrays (GFET arrays) in a large scale. The GFETs show extremely high electrolyte-gated transconductance promising exceptional biosensing capability. Signal-to-noise ratio (SNR) of the GFETs is analysed for different graphene areas. In the future we will apply these GFETs for extracellular recordings from neuronal and cardiac cells.
