Preparation of Microfluidic Chips by Electroplating and Used for Microdroplet Study

Abstract Microfluidic chips have been widely used in chemical industry and biological monitoring. The application of microfluidic chips in biological analysis, chemical synthesis, clinical detection and other fields not only makes the chemical reaction system small and highly integrated, but also reduces the sample consumption. At present, the traditional microchannel machining methods, such as laser etching and injection molding, have many disadvantages such as complicated process, high technical requirements, high cost and long cycle. In this paper, a new method of microstructure and microchannel in microfluidic chips based on electroplating technology is proposed based on traditional methods, and the microdroplet experiment was carried out.
