biosensor(1) A sensor which collects data on a biologic or physiologic process—e.g., blood pressure, temperature, etc.
(2) A biomolecule or system—e.g., enzyme, receptor, antibody, organelle or cell—coupled to a microelectronic system or optical probe to enable rapid, accurate, low-level detection of substances in body fluids, water and air. Biosensors have been used to measure glucose, creatinine, ethanol, gamma globulin, lidocaine, nerve gases, penicillin, sodium ions, testosterone, theophylline, vitamin B12, and O2.

biosensor(bī′ō-sen″sor″) [ bio- + sensor]
1. A device that senses and analyzes biological information, including temperature, heart rate, blood pressure, or the chemical composition of body fluids.
2. A device that incorporates some biologic agent (e.g. an enzyme) as a part of its sensing capability.

biosensora biological material such as an ENZYME, an ANTIBODY, a MICROORGANISM or other biological system, coupled to an appropriate transducing system, which act together to monitor a specific biochemical reaction and convert it into a measurable electrical signal. Biosensors may be used in health care, for example to measure specific METABOLITES in the body, and in the monitoring of pollutants in the environment. The enzyme glucose oxidase is used in the biosensor for monitoring GLUCOSE levels in the blood.
