Abstract: Continuous flow-based cell separations are indispensable for many biomedical applications and diagnostics including early detection of cancer. Here, we describe a high-throughput cell separation technique for sorting circulating tumor cells (CTCs) from blood using microfluidics. The separation consists of a 2-step process to efficiently isolate CTCs from blood. In the first step, 99% of hematologic cells (erythrocytes (RBCs) and leukocytes) are removed using shear-modulated inertial focusing with >90% CTC recovery. This RBCs depleted sample is then run through a low aspect ratio spiral microchannel to completely isolate the CTCs. The operating principle of this separation method exploits the difference in cell size between CTCs (∼16-20 μm diameter) and other blood cells (RBCs ∼8 μm; leukocytes ∼8-14 μm).
