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.

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.
