摘要: The present disclosure in some embodiments provides a flow cell sorting system, a focus detection method, as well as a fluidic chip. In one aspect, the fluidic chip comprises a cover sheet and one or more substrate layers, and one or more channels in each of the fluidic chips. In one aspect, the cells or other analytes in a sample are focused onto the same plane as they flow through the fluidic channel. In another aspect, the cells or other analytes on the same plane are irradiated with the same light intensity, for example, by a flat-top laser beam. This combination eliminates or reduces variation caused by cells at different positions receiving different intensities of the excitation light, and therefore improves accuracy of the flow cytometry analysis. In another aspect, a sorting apparatus is designed at the junction of the detection area and the outlet channel to separate the target cells.
