Description

technical field [0001] The invention relates to the technical field of cell detection and analysis, in particular to a cell sorting system and method. Background technique [0002] It is of great research significance to realize the classification and screening of homogeneous or heterogeneous cells. Traditional cell sorting methods include centrifugation, microfluidic methods, microporous sieve methods, immunomagnetic bead methods, and flow cytometry. For the measurement of the physical characteristics of cells, the micropipette and microfluidic chip methods are usually used at present. The above two methods have fixed sizes for the key measurement parts during the sorting process, which makes it often difficult to Due to the problem of size mismatch, not enough effective data can be obtained, resulting in low sorting efficiency. Contents of the invention [0003] Based on this, it is necessary to provide a cell sorting system and method capable of improving sorting effi...
