摘 要：The technology supporting the development of electrochemical biosensors is a high interest area of current research programs. Broad interdisciplinary skills are required for the design and construction of these devices. To provide a brief overview of these biosensors, it is helpful to (1) define what is meant by a biosensor (2) explain the attributes and properties of an effective sensor. The detection approach is electrochemical in origin. This is a technical discipline that constitutes an area of specialization in its own right. The applicable biomaterials and how they produce detection signals brings together biochemical sciences with electrochemical phenomena. Finally a discussion of the immobilization technologies is presented. This yields a useful biosensor which is a significant materials science development effort. Also, list of references is presented that can lead the reader to current texts and major review articles addressing the technology in greater detail.
