Recent Advances in Materials for Enzyme-free Electrochemical Glucose Sensors

Abstract

Glucose is not only the main energy source of living cells but also an important metabolic intermediate product of organisms.Its detection and analysis are of great significance in the diagnosis and treatment of human diseases, especially diabetes.We discuss the progress in research on electrochemical enzyme-free glucose sensors in recent years and the electrochemical mechanism and glucose-sensing properties of various materials, including metals, metal oxides, and carbon nanomaterials and their nanocomposites.Finally, the prospects for the development of enzyme-free glucose sensors are outlined.
