Biosensors measure several biological properties, including biomolecular kinetics, presence and concentration of biomolecules, strength of molecular interreactions, and location of cellular binding sites. Instrumentation typically includes a detection system, biosensor chips, and reagents.
Academia accounts for over a third of worldwide demand for biosensors, which are used primarily in biochemistry and molecular biology, in the study of cell communication, immune response, neurobiology, and mechanisms of infection. The pharmaceutical and food/beverage industries also account for a significant portion of biosensors demand.
