INTRODUCTION
Biosensors, which combine a selective biological element (antibody, enzyme, cell, etc.) with a transducer, enable the rapid detection and/or quantification of the presence of certain biomolecules in food, the environment or biological fluids (blood, urine, etc.). Their compactness, high specificity, sensitivity and portability are all reasons to believe that, in the long term, they could supplant existing techniques in this field. Over the last twenty years, the number of bibliographic references including the term "biosensor" in the title or abstract has grown exponentially: from 9 references in 1988, this number rose to 756 in 2007, demonstrating the craze surrounding these technologies.
Since the pioneering work of Clark and Lyons
This article presents the various biosensor technologies developed in recent years and reviews their applications.
