Z-stacked fast camera imaging (225,000 fps) results for particle focusing in devices with different curvature angles:(a) 70°; (b) 90°; (c) 135°; (d) 225°; and (e and g) 180°. Sample flow rate for all the devices was 25 µl/min while optimized vertical sheath fluid rate for each device is 410, 337, 180, 110, and 90 µl/min for 70°, 90°, 135°, 180°, and 225°, respectively. (f) The focusing of 1.9 µm polystyrene beads by the 180° channel device. The focusing diameter is 2.8 µm. (h) The focusing of 10.11 µm polystyrene beads by the 180° channel device. The focusing diameter is ~11.61 µm.
