Research progress of electrode materials for non-enzymatic glucose electrochemical sensors

Abstract

Glucose biosensors are mainly divided into two types. Traditional enzymatic glucose sensors with high sensitivity and selectivity were developed and used early; however, they are sensitive to temperature and pH and come at a high cost. In contrast, non-enzymatic glucose sensors have been widely studied because of their stability and economy. Their research directions mainly focus on improving the detection ability and immediacy. Under these research directions, different electrode sensitive materials have been continuously developed and studied. This article reviewed the research progress of non-enzymatic glucose electrochemical sensor sensitive materials in the past five years. We also introduced the basic principles of electrochemical detection, various electrode sensitive materials and the development direction of non-enzymatic glucose sensors.
