Nonenzymatic glucose detection at ordered mesoporous carbon modified electrode

This work reports on a novel nonenzymatic amperometric glucose sensor based on the ordered mesoporous carbon (OMC). Amperometric method was used to evaluate the electrocatalytic activity of the OMC modified electrode toward nonenzymatic glucose in alkaline media in presence and absence of chloride ions. The results indicated that OMC showed electrocatalytic activity for the oxidation of glucose in alkaline solution. The resulting biosensor exhibited excellent performance for glucose determination with high sensitivity of 10.81 mu A/mM and a low detection limit of 0.02 mM. The OMC modified electrode is also to resistant the interference from common interfering substances such as ascorbic acid, dopamine and uric acid. (C) 2009 Elsevier B.V. All rights reserved.
