Glucose Biosensors: 40 Years of Advances and Challenges

Forty years have passed since Clark and Lyons proposed the concept of glucose enzyme electrodes. Excellent economic prospects and fascinating potential for basic research have led to many sensor designs and detection principles for the biosensing of glucose. Indeed, the entire field of biosensors can trace its origin to this glucose enzyme electrode. This review examines the history of electrochemical glucose biosensors, discusses their current status and assesses future prospects in connection primarily to the control and management of diabetes.
