Novel ECPs (electronic conducting polymers) based on amino β-styryl-substituted terthiophene (AST) were synthetized by direct electropolymerization. The ECPs were characterized by cyclic voltammetry, square-wave voltammetry, Fourier transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). The poly(amino β-styryl terthiophene) displayed cyclic and square-wave voltammograms with redox peaks that can be assigned to the aminophenyl moiety and the polyterthiophene backbone. The presence of free primary amine groups on the ECP film permitted further biological functionalization (i.e., covalent bonding of various bioreceptors on its surface). The electrochemical performance of Biotin grafted at the AST modified glassy carbon electrode was investigated to detect the Avidin protein in solution by cyclic voltammetry and square-wave voltammetry.Key words: electronic conducting polymer, electrode surface modification, biosensor, β-styryl-substitued terthiophene, functionalization, cyclic, square-wave voltammetry.

In order to a better characterization of a graphite-polyurethane composite intended to be used as a voltammetric sensor, the performance in a square wave voltammetric procedure was investigated. Using hydroquinone (HQ) as a probe, the electrode showed to be useful in square wave voltammetry with limit of detection of 0.28 µmol L-1, with recoveries between 99.1 and 101.5%. The results of the proposed method agreed with HPLC ones within 95% confidence level.
