Abstract

Disclosed is an approach to differentiating between different particle types in samples flowing through microfluidics chips. A sample may have an initial proportion of a first cell type to a second cell type. An illuminating light source may emit a coherent light at the sample, and light leaving the chip in a first direction may be detected using a first light detector, and light leaving the chip in a second direction (e.g., orthogonal to the first direction) may be detected using a second light detector. The detected light may be fluorescence. An orientational feature of a plurality of cells in the sample may be determined based on the light detected by the detectors. Based on the orientational features and the detected light, a biasing operation may be performed for each cell in the sample to obtain a modified proportion of cell types in the sample.
