From: Functionalization of an extended-gate field-effect transistor (EGFET) for bacteria detection

Transfer characteristics of EGFETs with RFG = 10 MΩ (a, circles), RFG = 10 GΩ (b, triangles), and RFG = 50 GΩ (c, diamonds) contacted with a bacteria suspension each in comparison to only the transducer (squares).
