Normalized electrical output (I/I₀) vs. time of a single operating device. (a-b) Response curves to passivation upon addition of successive aliquots of BSA. (c) Response for a nanowire device functionalized with Fn. Inset (1) is the device configuration during active sensing measurement. Inset (2) shows the plateau and the definition of response time. Inset (3) is schematic of a control device without Fn capture probe does not respond to the presence of N protein. Images reprinted from (Ishikawa et al., 2009a).
