This review deals with a survey of analytical methods for the determination of hydrogen peroxide. Since high concentrations of this simple compound may cause diseases connected with oxidative stress like cancer, cardiovascular disorders, and Alzheimer disease, its monitoring is very essential. Therefore, cheap, sensitive, selective and fast electrochemical methods are desirable for its detection. Various electrode materials based on carbon, silver, gold and platinum are described here, as well as their applications to analysis of various samples. Biosensing applications with ultramicroelectrodes allow one to detect H2O2 directly in cells which helps to understand in depth their oxidative stress and other processes connected with the production of hydrogen peroxide.
