Abstract

The invention provides a three-channel microsphere screening chip which is characterized in that a screening channel which is 30mm in length and 2.0mm in width is formed in a rectangular chip body, one collecting channel is formed in each side of each screening channel; the screening channels are communicated with the collecting channels through screening fence holes; three fences are arranged inside the screening fence holes; and anti-blocking columns are arranged outside the screening fence holes. The invention further provides an operation method of the chip body. The three-channel microsphere screening chip is relatively high in specialty, can be directly connected and used with capillary tubes of a production line, convenient and simple to manufacture and low in cost as multiple chips of different specifications can be combined randomly, and the screening efficiency is improved.

Description

technical field

[0001] The invention relates to a new type of microsphere screening chip. In terms of use, it is a three-channel microsphere screening chip used in materials science and medicine and its use method. Background technique

[0002] At present, the large-scale use of oil-water O / W dual-phase technology to produce particles has been widely used in production, but the size screening of particle materials mostly uses the traditional method of filtration or dry particle sieving. It is not very convenient to screen the microspheres prepared by using liquid, especially for the micron particle size, it is easy to make the filtration invalid, or the filtration time is very long; if the microspheres are dried and then sieved, the above problems also exist. The production cost of drying due to exceeding the standard particles has been increased. Microfluidic chips are a new technology developed in recent years. For micron droplet particles, they have the characteristics o...
