With the continuous development in microfluidic fabrication technology, microfluidic analysis has evolved from a concept to one of research frontiers in last twenty years. The immunoassay methods based on microfluidic devices have also made great progress. Such devices consist of microchannels for transporting fluids integrated with part or all of the necessary components of an imrnunoassay procedure. Mierofluidic technology improves greatly the analytical performance of immunoassays by reducing the consumption of reagents, decreasing the analysis time, and developing automation. This review focuses on the development and classification of microfluidic immnnoassays, and the characteristics of each type of chips and their performances are also discussed.
