Glucose Biosensor: Basic Principles, Evolution and Practical Application

Abstract

Glucose biosensors can detect the abnormal level of blood glucose levels, which plays an essential role for the initial phase of treatment in clinical practice. The association between fast plasma glucose (FPG) levels and presence of retinopathy to identify the threshold of glucose level with specific value which help to confirm whether or not getting the disease. Glucose biosensors measure the concentration of blood glucose by using the linear relationships between different molecules’ consumption or formation. Glucose biosensors can still be altered by reducing used potentials, increasing durability and enhancing reproducibility. Some practical applications of glucose biosensors in day-to-day life include healthcare, pharmacy, food, agriculture and so on. In food products, the concentration of glucose can be an indicator of its quality and help control the amount of sugar consumed. In other areas, the measurement of changes in glucose levels when interacting with drugs will lead to different strategies used for treatments. This article contains the basic principles of glucose biosensor, some benefits and drawbacks of four generations and related applications.
