Study on detection methods for H2O2 in biological samples

Abstract

Hydrogen peroxide (H2O2) plays significant roles in regulating diverse biological processes such as immune cell activation, vascular remodeling, apoptosis, stomatal closure and root growth. Many studies have suggested that an excessive amount of H2O2 will induce various kinds of biological damage, leading to aging, neurodegeneration, as well as many other diseases. Thus, determination of H2O2 in trace level in biological and various water samples is of great importance. In this article the studies of detection methods for H2O2 in biological samples in recent years are reviewed.
