Abstract

Hydrogen peroxide (H2O2) is not only a product of the reactions catalyzed by a large number of highly selective oxidases but also an essential mediator in food, pharmaceutical and environmental analysis. Therefore its determination is of paramount importance in many areas in chemical, biological and clinical fields. Most H2O2 biosensors developed till date are based on enzymes and proteins which have a limited sensor life. Moreover, complex procedures are followed for sensor fabrication. Therefore an inorganic material based sensor with a simple design and longer shelf-life is highly desirable. In this work, the development of a novel cerium oxide nanomaterial based electrochemical sensor for the measurement of hydrogen peroxide is described. This has direct ramifications in the development of sensors for other superoxide radicals. Copyright © 2005 by ASME.
