Sensor sensing tests with I-V and FET measurements.
(a) Direct current measurement results of the VG sensor modified with Au NP-anti-IgG conjugates, BB and IgG. Inset is the typical FET curve of the VG sensor. (b) Transistor mesurement results of the VG sensor modified with Au NP-anti-IgG conjugates, BB and IgG (2 ng/mL). (c) Transistor mesurement results of the control VG sensor without Au NP-anti-IgG conjugates. (d) Transistor mesurement results of the control VG sensor without the BB. For FET measurements, Vd = 0.1 V unless otherwise specified.
