A biosensor is an analytical device used to detect a chemical substance that combines a biological component with a physicochemical detector. The sensitive biological component, e.g. tissue, microorganisms, organs, cell receptors, enzymes , antibodies, nucleic acids, etc., is a biologically derived material or biomimetic component that interacts, binds, or recognizes with a biological substance. Biological engineering can also create the biologically susceptible elements. The transducer or detector element, which transforms one signal into another, works in a physicochemical manner: optical, piezoelectrical, electrochemical, electrochemical, etc.
