英文摘要:

      Biosensor, as a new type of testing tool in the interdisciplinary field, has drawn the attention of researchers. Interdigitated microelectrodes are widely used in food safety and medical treatment for their advantages of high sensitivity, fast response, low limit of detection, moderate cost and convenient portability. One of the key factors that influences the interdigitated microelectrodes sensor is the structural parameters. This paper reviewed the material, structure simulation, structural experiment and modification of interdigitated microelectrodes, introduced the effects of structural simulation, experimental analysis and surface modification on the capability of the sensor in detail, also summarized the short comings of the interdigitated microelectrodes through a series of analysis and research, and prospected the future development trend.
