Poly(2-uoroaniline) has been electrochemically deposited on ITO coated glass plates in the form of thin lms using 4 M per-chloric acid as electrolyte. These polymeric lms have been spectroscopically characterized by FT-IR and UV-visible spectropho-tometric methods. Room temperature electrical conductivity of the polymeric lms was measured and found to be lower than that ofpolyaniline lms. The SEM studies show the blunt needle like surface morphology of the polymeric lm.physical adsorption method. The redox characterization of poly(2-uoroaniline) and poly(2-uoroaniline)/GOX lms has beencarried out by cyclic voltammetry technique. Amperometric detection ofb-glucose was carried out by using the above enzymeimmobilized polymeric lm as a working electrode and Ag/AgCl as a reference electrode at a bias voltage of 0.2 V over a physi-ological range. The electrode carrying GOX was found to be stable up to 32 days.. 2002 Elsevier Science B.V. All rights reserved.
