Immobilized anthraquinone for redox mediation of horseradish peroxidase for hydrogen peroxide sensing

Dou, Yuehua; Haswell, Stephen; Greenman, John; Wadhawan, Jay

Abstract

The detection of hydrogen peroxide is detailed using horseradish peroxidase and anthraquinone. Both species are immobilized on a glassy carbon electrode substrate. This dual immobilization gives rise to lower detection limits compared with the situation when either of the species is immobilized. Detection limits of 40 nM are reported within physiologically-relevant media. (C) 2009 Elsevier B.V. All rights reserved.
