Figure S3. Transfer characteristics of GFETs in 1 mM potassium phosphate buffer pH 7 before and after the addition of QueF-Y5Y and a nitrile. a) Single representative channel, b) aggregate measurements with thick line indicating the mean value and the shaded area ± 1 SD (preQ0 N=7, BnCN N=6). Arrows indicate direction of gate voltage change with time.
