biosensor

Any device that detects, records or transmits physiological data, especially data concerning the presence of chemical compounds (analytes)

Since the early 1980s, considerable research effort has been devoted to the development of fiber optic (FO) biosensors because of their potential sensitivity, detection speed, and adaptability to a wide variety of assay conditions.

A device that uses biological material (e.g. microorganisms, oligonucleotides, enzymes, antibodies) to detect other biological molecules or chemicals.

Today's biosensor market is dominated by glucose biosensors, mass-produced enzyme-electrodes for the rapid self-diagnosis of blood glucose levels by diabetes sufferers.
