ABSTRACT

Enzymatic biosensors



Eduardo Torres Ramírez, Alia Méndez Albores


The first enzymatic biosensor proposed by Lions and Clark in 1962 for the measurement of glucose in blood proved the high efficiency of the enzymes as recognition elements in biosensors. Thus, a great variety of devices have been developed using enzymes as biological recognition element for analytic detection in several areas such as environmental, food and medicine. This paper describes the enzymatic biosensor in a simple way, emphasizing in the electrochemical type as the most commonly used. Several examples of enzyme biosensors are exposed in areas where they have a significant impact. We conclude from this analysis that the enzyme biosensors have enormous technological potential due to high sensibility of detection and quantification, reproducibility, selectivity, precision and accuracy.
