Abstract: The glucose sensing properties of diamond and carbon nanotube (CNT) electrodes were evaluated comparatively. Amperometric glucose sensors had been constructed on boron-doped diamond (BDD) and CNT electrodes based on the immobilization of glucose oxidase (GOD) on 3,3′-diaminobenzidine (DAB)-electropolymerized electrode surface. DAB forms a self-limiting layer with NH2 functional groups for tethering to GOD molecule. The cyclic voltammograms of DAB on BDD and CNT revealed important structural differences between the two electrode surfaces. Modification with DAB allowed the CNT to show selective response to glucose at a lower electrode voltage of 0.3 V, and with suppressed interference signals from ascorbic acid (LAA) and uric acid (UA). No selective response to glucose was obtained from DAB-modified BDD electrode. © 2003 Elsevier B.V. All rights reserved.
