Biosensor

In situ biosensors are instruments that are sensitive to biological substances and convert their concentration into electrical signals for detection. It is an analytical tool or system composed of immobilized biosensitive materials as recognition elements (including enzymes, antibodies, antigens, microorganisms, cells, tissues, nucleic acids, and other bioactive substances), appropriate physical and chemical transducers, and signal amplification devices. Biosensors have the functions of receivers and converters.
