It is of great significant to deeply understand the life progress and promote medicine developments using appropriate techniques to characterize interaction between biomolecules. Microfluidic chip electrophoresis technique which combines microfluidic chip with capillary electrophoresis possesses many advantages including rapid, high performance,high throughput, low sample consumption and easy of integration, etc. It has already demonstrated great potential just in the early stage of application. In this paper, the separation mode, analysis methods and detection techniques in chip-CE biological binding constant and binding mechanism are reviewed respectively. The chip-CE is also simply compared with micro-array chip biomolecular interaction analysis. Finally, the development prospects and present situations in chip-CE are analyzed.
