DIELECTRIC SPECTROSCOPIC STUDIES ON POLYPYRROLE GLUCOSE-OXIDASE FILMS

An investigation was made into the dielectric spectroscopic characteri stics of p-toluene sulfonate (PTS) doped polypyrrole (PPY) films in th e presence and absence of immobilized glucose oxidase (GOX) in three d ifferent configurations: Al-PTS-PPY-Al, Al-PTS-PPY/GOX-Al, and Al-PTS- PPY/GOX/beta-D-glucose-Al, respectively. Measurement of dielectric los s and capacitance yielded valuable information about the dielectric pr operties of GOX immobilized in PTS doped PPY films. The effect of both the temperature and varying beta-D-glucose concentrations on the mobi lity of the charge carriers in these films was also systematically stu died. (C) 1996 John Wiley & Sons, Inc.
