Direct electrochemistry and electrocatalysis of hemoglobin immobilized on carbon paste electrode by silica sol-gel film.

Abstract

Direct electrochemical and electrocatalytic behaviors of hemoglobin (Hb) immobilized on carbon paste electrode (CPE) by a silica sol-gel film derived from tetraethylorthosilicate (TEOS) were investigated for the first time. Hb/sol-gel film modified electrodes showed a pair of well-defined and nearly reversible cyclic voltammetric peaks for Hb Fe(III)/Fe(II… (More)
