Dielectric spectroscopic studies on polypyrrole glucose oxidase films

Abstract

SYNOPSISAn investigation was made into the dielectric spectroscopic characteristics of p-toluene sulfonate (PTS) doped polypyrrole (PPY) films in the presence and absence of immobilized glucose oxidase (GOX) in three different configurations: A1-PTS-PPY-A1, A1-PTS-PPY/ GOX-Al, and Al-PTS-PPY/GOX/@-D-glucose-Al, respectively. Measurement of dielectric loss and capacitance yielded valuable information about the dielectric properties of GOX immobilized in P T S doped PPY films. The effect of both the temperature and varying @-D-glucose concentrations on the mobility of the charge carriers in these films was also systematically studied. 0 1996 John Wiley & Sons. Inc.
