Nanomaterial-Based Electrochemical Hydrogen Peroxide Biosensor

Abstract

Hydrogen peroxide (H 2 O 2 ) is well-known oxidizing, bleaching agent and also one of the significant by-products of diverse regulating biological processes. It has been recognized as a threat in the progression of atherosclerosis, renal disease, ageing and other diseases. Hence, determination of H 2 O 2 in trace levels in biological samples is of great importance. This article briefly reviews the electrochemical detection method for hydrogen peroxide sensing, including the nanomaterial based enzyme-containing and non-enzymatic biosensor. The biosensor can achieve microscopic detection of hydrogen peroxide. It also discusses the performance and future prospects of the electrochemical H 2 O 2 biosensor.
