Brief introduction: Microfluidics chip technology (Microfluidics) integrates the basic operating units of biological, chemical and medical analysis process, such as sample preparation, reaction, separation and detection, onto a micron scale chip and completes the whole process of analysis automatically. Due to its great potential in the fields of biology, chemistry, medicine and so on, it has developed into a new and interdisciplinary research field of biology, chemistry, medicine, fluid, electronics, materials and machinery. Microfluidic chip is a hot spot in the development of Miniaturized Total Analysis Systems. Microfluidic chip analysis takes microchip as operating platform, based on analytical chemistry, relying on microelectromechanical processing technology, taking micropipeline network as structural feature, taking life science as the main application object at present, and is the focus of current development in the field of microwhole analysis system. Its goal is to integrate the functions of the entire laboratory, including sampling, dilution, reagent addition, reaction, separation, detection, on microchips, and can be used multiple times. Microfluidic chip is the main platform of microfluidic technology. The device is characterized mainly by its effective fluid-absorbing structure (channels, reaction Chambers and some other functional components) at least on a scale of micron in one latitude. Because of the micron scale structure, the fluid shows and produces special properties different from the macro scale. Therefore, unique analytical generation performance is developed. Features and development advantages: Microfluidic chip has the characteristics of controllable liquid flow, few sample and reagent consumption, and the analysis speed can be increased ten times to 100 times. It can conduct simultaneous analysis of hundreds of samples in a few minutes or even shorter, and the whole process of sample pretreatment and analysis can be realized online.
