Abstract: Miniature, automatic and integrated with high throughput and rapid analysis, the microfluidic chip technology has brought revolutionary changes in laboratory experimentation in recent years and has been widely used in many research-based field, such as biochemistry and medicine. However, microfluidics is not yet introduced into home-made totally-integrated automation DNA analyzers. This paper has summarized the applications of microfluidics in DNA rapid testing, including DNA extraction, PCR amplification and electrophoresis separation, especially the advance of forensic DNA rapid detection. In addition, it also discussed the research state of the totally-integrated DNA analysis at home and abroad. Currently, full integration and versatility are the mainstream direction of microfluidic technology research. With the help of this system, rapid and real-time forensic DNA testing will not only be conducted in laboratories, but also at crime scenes and even in everyday lives.
