An 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: Al‐PTS‐PPY‐Al‐PTS‐PPY/GOX‐Al, and Al‐PTS‐PPY/GOX/β‐ D ‐glucose‐Al, respectively. Measurement of dielectric loss and capacitance yielded valuable information about the dielectric properties of GOX immobilized in PTS doped PPY films. The effect of both the temperature and varying β D ‐glucose concentrations on the mobility of the charge carriers in these films was also systematically studied. © 1996 John Wiley & Sons, Inc.
