Title: pH-Sensitive syringaldazine modified carbon ceramic electrode for bioelectrocatalytic dioxygen reduction
Abstract: Voltammetrically stable water insoluble (syringaldazine) modified was obtained by sol-gel processing of methyltrimethoxysilane sol with dissolved syringaldazine together with dispersed graphite This silicate carbon ceramic electrode exhibits stable corresponding to the surface confined oxidation-reduction The pH dependence of the immobilized syringaldazine redox obeys the Nernst equation in the range of 3-10. After further with extracellular lyophilized laccase from Cerrena encapsulated within a thin hydrophilic silicate film the exhibits catalytic activity towards dioxygen reduction. Both current and potential are pH dependent. (c) 2007 Elsevier B.V. All rights reserved.
