Abstract

The invention discloses a cell sorting system and method. The system comprises a signal generator, a power amplifier, a relay and an ultrasonic transducer device, wherein the signal generator is connected with the power amplifier, the power amplifier is connected with the relay, and the relay is connected with the ultrasonic transducer device; the signal generator and the power amplifier are used for generating ultrasonic signals of target-frequency target acoustic energy, and the relay is used for controlling on-off state of the ultrasonic signals; the ultrasonic transducer device comprises an ultrasonic transducer, an ultrasonic transducer cover and a phonon crystal plate, the ultrasonic transducer is arranged at the top in the ultrasonic transducer cover, the phonon crystal plate is arranged at the bottom of the ultrasonic transducer cover, the ultrasonic transducer is used for receiving the ultrasonic signals, the phonon crystal plate is used for generating target radiation force according to the ultrasonic signals, and the target radiation force is used for attracting cells with a target size. By the adoption of the system or method, the sorting efficiency of cell sorting can be improved, and damage to the cells can be avoided.

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...
