A novel sensitive and stable phenols amperometric biosensor, based on polyaniline–polyacrylonitrile composite matrix, was applied for determination of benzoic acid. The electrochemical biosensor functioning was based on the inhibition effect of benzoic acid on the biocatalytic activity of the polyphenol oxidase (PPO) to its substrate (catechol) in 0.1M phosphate buffer solution (pH 6.5). A potential...
A novel one-step approach to glassy carbon nanoelectrode ensembles (NEEs) with the pores of 20–120nm in radii has been developed using an amphiphilic block copolymer [polystyrene-block-poly (acrylic acid)] self-assembly. This procedure is simple and fast, and requires only conventional, inexpensive electrochemical instrumentation. Electrochemical methods were used to characterize the NEEs prepared...
A novel biosensor for phenols was constructed by immobilizing polyphenol oxidase (PPO) into polyaniline-polyacrylonitrile composite matrix. The sensing film was prepared by electropolymerization of aniline into polyacrylonitrile (PAN)-coated platinum electrode in the presence of PPO. The scanning electron micrographs (SEM) showed that PAN had microporous structure and polyaniline and the enzyme could...
