Abstract

The utilization of semiconducting and conducting polymers for the fabrication of computer-assisted printable-on-demand electrodes (the so-called “biopolytronics” concept) is a very interesting field of investigation for the realization of third generation bioelectronic devices such as biosensors, biofuel cells,…. In this line, we studied in the last years fully inkjet printed glucose oxidase (GOD)-based electrode, realized over ITO substrates [L. Setti, A. Fraleoni-Morgera, B. Ballarin, A. Filippini, D. Frascaro, C. Piana, Biosens. Bioel., 2005, 20, 2019; L. Setti, C. Piana, S. Bonazzi, B. Ballarin, D. Frascaro, A. Fraleoni-Morgera, S. Giuliani, Anal. Lett., 2004, 37, 1559]. For enhancing the performances of these devices a deeper understanding of the phenomena of electronic transfer between inorganic electrodes such as ITO, and organic materials able to conduct electrical currents, such as for example PEDOT:PSS, is needed. In this view, we realized surface modifications of ITO at a nano-scale, and we investigated the effect of such a treatment over the performances of inkjet printed GOD-based electrodes. In particular, investigations over the ITO surface morphology (AFM, white light interferometer, SEM, etc) and electrical characteristics (sheet resistance) have been carried on, and related to the performances of devices fabricated and tested. Together with an overview of the technologies used for the realization of biological and electronic inks, as well as for printing enzyme-based electrodes, are reported.
