Schematic illustration of high-throughput, continuous-flow ternary separation of tumor cells and clusters from WBCs in large volumes of pleural or abdominal effusions using our spiral-contraction-expansion device. The spiral-contraction-expansion channels include slanted spiral channels with (i) a trapezoidal cross-section and (ii) periodic expansion structures designed at the outer wall.
