Problems solved by technology

At present, improving the efficiency of droplet generation is often to increase the yield of droplets by concentrating multiple structures. In the planar structure, due to space constraints, the degree of integration is relatively low, and the generation efficiency needs to be further improved; there are also three-dimensional integrated structures. Improve the efficiency of droplet generation, but there are generally problems such as poor consistency of terminal structure and relatively low integration

Abstract

The invention belongs to the technical field of droplet microfluidics, and particularly relates to an efficient droplet generation device. The device comprises a dispersed phase inlet layer and a liquid drop generation layer, and two-stage or multi-stage continuous phase grading layer formed by connecting N output ends of one input end in a tree-shaped structure, and the two-stage or multi-stage dispersed phase grading layer formed by connecting N output ends of one input end in the tree-shaped structure; wherein N is a natural number and is greater than or equal to 3; the output end of each dispersed phase grading layer is connected with a dispersed phase inlet layer, and each dispersed phase inlet layer is connected with the liquid drop generation layer; and the output ends of the continuous phase grading layer are connected with the droplet generation layer one by one. According to the efficient liquid drop generation device, the conditions of all positions of the liquid channel arecompletely the same, generated liquid drops have good uniformity and consistency, and meanwhile production efficiency is effectively improved through hierarchical arrangement.

Description

technical field [0001] The invention belongs to the technical field of droplet microfluidics, and more specifically relates to an efficient droplet generation device. Background technique [0002] Droplet microfluidics is an important branch of the field of microfluidics. One fluid is dispersed in another immiscible fluid in the form of droplets, and droplets are used as the basic operation and reaction unit. Droplet microfluidics has unique advantages and can be widely used in biology, chemistry, materials science, engineering and other fields, and has great application prospects. For example, the currently commercialized microdroplet PCR can greatly shorten the time, microdroplets can be used as microreactors to efficiently detect and screen trace chemical substances, and droplet microfluidics can achieve highly uniform preparation of materials. [0003] Efficient and uniform preparation of micro-droplets is the prerequisite for the application of micro-droplets. At prese...
