a Schematic of the back-gated MoS2 transistor. b Optical microscopy image of the MoS2 channel material between the source and drain electrodes. c The real-time current responses to different glucose concentrations. d The response current Ids of the MoS2 FET as a function of glucose concentrations, from 0 to 30 mM. The inset shows the response current extracted for lower glucose concentrations, from 0 to 1.0 μM. Reprinted under CC BY-NC 3.0 from [44]
