Abstract

A device for manufacturing micro-droplets in a capillary tube is characterized by comprising the capillary tube, an elastic beam and a fixed base, one end of the elastic beam is fixedly connected with the fixed base, and the other end of the elastic beam is fixedly connected with the capillary tube.

Description

technical field [0001] The invention relates to the technical fields of micro-nano particle manufacturing, micro-nano droplet manufacturing by micro-channels, 3D printing, etc., and specifically relates to a device for making micro-droplets inside a capillary and a method for generating micro-droplets. Background technique [0002] With the development of fine processing, micro-nano-scale fluid phenomena have been widely concerned. Micro-droplets have the advantages of stable shape, easy manipulation, low cross-infection, and low cost. They have important applications in the fields of cell science, drug screening, protein crystallization, and material synthesis. [0003] The liquid column will be broken into small droplets under the action of interfacial tension, and this phenomenon is used to generate microdroplets in the microchannel. This has been widely used in inkjet printers, micro-nanoparticle manufacturing, etc. [0004] At present, the micro-droplets in the prior ...
