A sensor used to detect a biological substance (for example: bacteria, blood gases, or hormones). Biosensors often make use of sensors that are themselves made of biological materials or of materials that are derived from or mimic biological materials.

A portable analytical device that integrates a biorecognition molecule, such as an enzyme, an antibody, or DNA, with a signal transducer. The biorecognition molecule gives the biosensor the selectivity for the analyte while the transducer determines the extent of the biorecognition reaction and converts this to an electronic signal which is outputted to the user.
