Product description: In recent years, the ordered assembly of monodisperse nanoparticles has become an important means for the preparation of photonic (colloidal) crystal microspheres, ordered macroporous structure, cellular microcarriers, drug carriers and catalyst carriers. Especially, the preparation of colloidal crystal template materials with specific shape, controllable size and variable composition is still a challenge. It is undoubtedly a simple and effective method to confine the nanoparticles to a certain space by predesigned template, but it will be affected by the roughness and infiltration of the template. Furthermore, the assembly sequence of surface nanoparticles is poor. It is also difficult to separate from the template and the separation process is easy to cause damage to the surface structure. The liquid phase template can overcome these disadvantages. The microfluidic emulsion droplet preparation method greatly simplifies the emulsion droplet emulsification method due to its high design ability and fixed structure size. The efficiency of droplet formation and the repeatability of experiment are improved. Single dispersible microspheres with diameters ranging from micron to millimeter in diameter can be manufactured in batches (especially suitable for single dispersible microspheres with dimensions ranging from 50 microns to 500 microns). The traditional manufacturing method of microfluidic chip is to prepare two-dimensional or quasi-three-dimensional fluid channels by etching or soft template replication. The process is complex, the processing cost is high, and the encapsulation coupling condition of the chip is harsh. The fluid is often attached to the inner wall of the channel, and the infiltration of the channel has a greater impact on the fluid behavior. Therefore, it is necessary to carry out selective infiltration modification on different parts of the channel according to different requirements. The process is often complex and difficult to achieve the desired effect. In the three-dimensional microfluidic control system, the fluid does not need to contact the inner wall of the channel, which can avoid the disadvantages of the traditional microfluidic chip. As a result, capillary glass microfluidics has developed rapidly in recent years and is particularly suitable for scientific research. Nanjing caina biological technology co., LTD. Is able to provide a variety of capillary glass microfluidic chip products of different specifications. They have been verified by various precision instruments such as optical microscopy.
