“…Polymers have been used in the preparation of biosensors, which can quantify the hydrogen peroxide generated in the oxidation of sugars, the reaction is catalyzed by oxidase-type enzymes [1][2][3] . The hydrogen peroxide formed in the reaction of oxidation can be quantified by electrochemical methods and its amount is directly related with the sugar quantity.…”

The entrapment method was used to prepare electrochemical biosensors. Using controlled potential method, copolymers were synthesized between aniline y sulfonated-anilines in aqueous media at pH 4.9 on Platinum disc. The copolymers were characterized by elemental analysis and spectroscopy. Glucose-oxidase was entrapped in the electropolymerization process, at pH 4.9 in aqueous media. The copolymers modified electrodes and copolymer/enzyme were studied as working electrodes for the oxidation of different H 2 O 2 concentrations and indirect D-glucose quantification at pH 7, using controlled potential and the cyclic voltammetry methods (CV) correspondingly. A linear relationship between the hydrogen peroxide (or D-glucose) concentration and the electrochemical response was obtained at pH 7. The modified-electrodes displayed a fast time of current response, limited by the cycle numbers of the cyclic voltammetry, 232 s, and enough stability to allow for the measurements to be taken after several days.

“…In continuation of our work on conducting homo-polymers and co-polymers [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34], a conducting composite of poly(o-anisidine) (POA), poly(o-toluidine) (POT) and poly[(o-anisidine)-co-(o-toluidine)] (POA-co-POT) using incorporation of TiO 2 and SiO 2 was prepared by electrochemical polymerization. The characterization has been carried out by cyclic voltammetry, UV-Vis spectroscopy, conductivity measurements and thermogravimetric analysis (TGA).…”

A conducting composite of poly(o-anisidine), poly(o-toluidine) and poly(o-anisidine-co-o-toluidine) using incorporation of TiO 2 and SiO 2 was prepared by electrochemical polymerization. The films were electropolymerized in solution containing 0.1 M monomer(s), 1 M sulphuric acid as supporting electrolyte and 10 −5 M TiO 2 and SiO 2 by applying a sequential linear potential scan rate of 50 mV/s between −0.2 and 1.0 V versus an Ag/AgCl electrode. The characterization of the composites was done by cyclic voltametry, UV-Vis spectroscopy, electrical conductivity and thermogravimetric analysis. It is observed that the UV-Vis peaks appear in the region of the conducting emerladine salt (ES) phase. Overall, the polymers prepared using TiO 2 have higher conductivity than SiO 2 , with poly(o-toluidine)-TiO 2 conducting composite having the highest conductivivty. The composite does not lose its colour at higher temperature and, hence, can be utilized as conductive pigments required for anti-electrostatic applications.

“…The electrochemical devices made by different conducting polymers entrapping recognized biomolecules have been reported extensively (Habermuller & Schuhmann, 1998;Rahman et al, 2004;Selampinar et al, 1997), because their major advantages (Cosnier, 1999) are that polymer film can be polymerized with immobilizing enzyme in one step, and the film thickness can be controlled easily by adjusting capacity. The most common polymers used as matrixes to entrap enzyme are polyaniline (Borole et al, 2004), polythiophene, polypyrrole and its derivatives (Trojanowicz et al, 1995). In addition to enzymes, the mediators should be immobilized in the same matrix for biosensors or biofuel cells.…”
