Abstract

The characterization of functionalized electrodes by means of cyclic voltammetry constitutes an important step in the development of an electrochemical based biosensors. Herein an electrolyte gated thin-film transistor (EG-TFT) setup is proposed to acquire both cyclic voltammograms and transistor transfer characteristics using a semiconductor parameter analyzer. The redox behavior of a probe is studied in such a setup using the gate electrode of the EG-TFT as working electrode and it is compared to a conventional three electrode electrochemical cell setup. The complementary techniques acquirable by the EG-TFT setup are used to investigate protein immobilization via self-assembled monolayers on the surface of gold working electrodes.
