摘要：

The applications of transition metal hexacyanoferrates in electroanalysis are surveyed. Prussian Blue (ferric hexacyanoferrate) is recognized as the most promising low-potential transducer for hydrogen peroxide reduction among all known systems. The advantages of Prussian Blue over platinum or peroxidase electrodes for hydrogen peroxide detection are discussed. Various types of biosensors based on transition metal hexacyanoferrates and oxidase enzymes are considered. Amperometric biosensors based on Prussian Blue-modified electrodes allow the detection of glucose and glutamate down to 10(-7) mol L-1 in the flow-injection mode. The future prospects of Prussian Blue-modified electrodes in analytical chemistry for the monitoring of chemical toxic agents, in clinical diagnostics, and in food control are outlined.
