Abstract
Biological molecules such as enzymes and antibodies display a unique capacity to recognize and respond to other molecules in a way which can be exploited in the development of analytical devices. In a biosensor, the biological recognition system creates a physiochemical change proximal to a suitable transducer and thereby converts the concentration of the analyte into a quantifiable electrical signal. The design and construction of these devices requires an imaginative combination of biological, chemical, physical and engineering disciplines. Biosensors will find application in a variety of analytical fields.
