摘要：

Nanocomposite materials of poly(o-anisidine) (POAS) containing titanium dioxide nanoparticles (TiO2), carbon black (CB) and multi-walled carbon nanotubes (MWNT) were prepared. The synthesized materials were deposited in thin films in order to investigate their impedance characteristics by comparison. Electrochemical impedance spectroscopy (EIS) study was performed using the prepared films as working electrodes in a three electrodes configuration cell. Comparison between the fitting parameters was carried out in order to identify the improved nanocomposite for biosensor applications. (C) 2005 Elsevier B.V. All rights reserved.
