Organic electrochemical transistors (OECTs) rely on both efficient ionic doping/de-doping process and carrier transport in the mixed ionic-electronic channel under modulation of gate bias. Moreover, channels that hold photopatterning capability are highly desired to minimize parasitic capacitance simplify fabrication process/cost. However, yielding photo-patternable with precise/robust patterning controllable coupling is still challenging.

Abstract Electrochemical aptamer-based sensors are typically deployed as individual, passive, surface-functionalized electrodes, but they exhibit limited sensitivity especially when the area of electrode is reduced for miniaturization purposes. We demonstrate that organic electrochemical transistors (electrolyte gated with volumetric gating) can serve on-site amplifiers to improve sensors. By monolithically integrating an Au working/sensing electrode, on-chip Ag/AgCl reference and Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) counter — also serving channel transistor— we simultaneously perform testing traditional electroanalytical measurement on including cyclic voltammetry square-wave voltammetry.
