Figure 3

Transfer characteristics of (a, c, and e) Ag/AgCl and (b, d, and f) Au electrode gated μf-OECTs comprising PEDOT:PSS in the channel. The arrows represent the increase in Aβ aggregate (a and b) and Aβ peptide (c and d) concentrations in PBS from 2.21 fM to 221 nM. The inset of c depicts PEDOT:PSS’ chemical structure. The transfer characteristics of the pristine membrane (no CR functionalization) integrated devices are shown in e and f. The VD was −0.6 V for all devices. The sample solution in the fluidic channel was 1 μL.
