Abstract

The present invention provides a system and a method for preparing microcapsules, and relates to the technical field of materials. The system comprises a drive power supply, a piezoelectric ceramic, a bracket, a microfluidic chip, a micro pump, a micro spraying nozzle and a wall material reaction vessel. The method further comprises: injecting at least a solution to be prepared to the preparing system; emulsifying the injected solution to be prepared, such that the solution is in the micro-droplet form; and jetting the obtained solution having the micro-droplet form into the wall material solution so as to form the microcapsules through the reaction. According to the present invention, the microfluidic chip technology and the micro-jetting technology are firstly combined to carry out the metronomic microcapsule preparation, such that the mixing uniformity of the single component or multi-component solution and the capsule wall solution is enhanced, and the assurance is provided for the metronomic jetting of the microcapsules; and the microcapsule component configuration is flexible, wherein only the number of the inlet channels on the microfluidic chip and the channel geometry are changed so as to flexibly configure the number of the microcapsule components.

Description

technical field

[0001] The invention relates to the field of material technology, in particular to a system and method for preparing microcapsules. Background technique

[0002] Capsule or microcapsule reactor has broad application prospects in organic chemistry, analytical chemistry, molecular biology, medicinal chemistry, polymer chemistry, and nanomaterial preparation due to its unique structure and the special microenvironment it can provide. Its core idea is to construct a cell structure similar to living organisms consisting of molecularly recognized capsules and intracapsular cavities containing reaction media. In microcapsules, microparticles can be actively cultivated and proliferated, reducing the amount of exogenous environment. Effects on microparticles, such as cell particles. With the development of biological microcapsules, biologically active substances such as cells, enzymes, proteins and nucleic acids can be encapsulated in selectively permeable membranes....
