Abstract

The invention provides a microfluidic chip, a cell screening system, a control method and a microfluidic chip, the microfluidic chip comprises a chip main body, an import channel, a screening part andan export channel are arranged in the chip main body, the screening part is arranged between the import channel and the export channel, a plurality of screening units used for providing a liquid circulation channel between the import channel and the export channel are arranged in the screening part, a first inlet and a second inlet are further formed in the chip body, and the channel space of theimport channel is connected to the first inlet and the second inlet. The detection efficiency is effectively improved, and the duration of the detection process is shortened.

Description

technical field [0001] The disclosure relates to the field of biological detection, in particular to a microfluidic chip, a cell screening system and a control method. Background technique [0002] In various biological detection scenarios, it is necessary to use a cell screening device to separate target cells from a sample solution for further manipulation of the target cells. The target cells therein can be, for example, circulating tumor cells (CTC, Circulating Tumor Cells). Liquid biopsy technology represented by CTC technology has been applied in many aspects such as tumor screening, prognosis detection, and drug efficacy evaluation. [0003] In the existing related technologies, microfluidic chips can be used to screen cells. Specifically, the sample solution can be poured into the inlet channel, and after being screened and filtered by the screening part, the small non-target cells in the sample solution can be eliminated. The screening part enters the export chann...
