The Microfluidic System Based on Micro Immunosensor

As a key item of the research for the enhancement of the stability and consistency of micro immunosensor, the micro reaction cells and micro channels were designed and fabricated, based on microelectrode immunosensor chip. This design could help accomplish the immobiliza- tion of the biosensitive membrane and the immunoassay process. The technology and method for the enhancement of the stability and consistency of the micro immunosensor were put forward, and the performances of different structures used in the immunoassay system were analyzed and compared by FEA simulation. This work paves the way for the automation and utility of this kind of microsensor.
