|Definition:|| sensor that uses organic substances in the device, that is intended for measurement of organism-related subsystems, or that mimics an organism
Note 1 to entry: A typical biosensor consists of a biologically originated specific material such as an enzyme or an antibody that identifies the object of measurement and the device that measures a physical or chemical quantity change related to the identifying reaction. A semiconductor sensor or any of various types of electrode (e.g. ISFET, micro-oxygen electrode, and fluorescence detection optical sensor) prepared by silicon micromachining technology can be used as this device. Biosensors are used for blood analysis systems, glucose sensors, microrobots, and so on.
