Abstract

The purpose of biosensors in biochemistry and medicine is to provide a highly sensitive and selective method for reliable, rapid, and preferably continuous monitoring of certain chemicals and chemical processes in a biochemical and a physiological environment. In most cases, specific biochemical interactions between various biological ligands are utilized for the sensing of binding events. The sensor’s input is a physical property or an interaction of a physical, chemical, or biochemical nature. This input is processed via the sensor’s transduction element into a recordable signal.
