A New Biosensor for Glucose Based on Carbon Paste and Enzyme Immobilized onto the Polyaniline Film
Original language description
Conductive polymer polyaniline (PANI) was electrochemically synthesized by controlled potential cycling as a film at the surface of a carbon paste electrode (CPE) from acidic aqueous solution containing 1 M HCl and 0.25 M aniline. The characterization ofthe PANI-CPE was carried out with the aid of cyclic voltammetry in 1 M HCl, obtaining three couple of peaks from which the two pairs were distinct, having proved the electroactivity of the PANI film. Then, the PANI-CPE system was for the first time usedand tested as glucose biosensor, when the respective enzyme was potentiostatically immobilized onto the surface from 0.1 M phosphate buffer (pH 7.5) with 0.75 mg/mL GOD. Optimal conditions for the enzyme immobilization were investigated and the biosensor tested for glucose sensing within the concentration range of 1-500 mg/L D-glucose. All preliminary assays with the GOD/PANI-CPE configuration have shown favorable operational features of this new carbon paste biosensor whose further dev
