Distribution of deflected microdroplets without or with the magnet. (a) There is no magnet near the microfluidic channel. 73.5% and 67.4% of the empty and high-density droplets (diameter of 160 µm), respectively, pass through the point near the centerline of microchannel (840 µm away from the magnet) with the flow rate of 820.14 µm s⁻¹. There is little gap between the empty and high-density droplets. (CONTROL) (b) The magnet is located 1205.61 µm away from and the mid position of the main microchannel. 75.8% of the empty and 60.0% of the high-density droplets (diameter of 160 µm) pass through the point where the distance from the magnet is 480 µm and 600 µm, respectively. Fraction data and error bars are mean ± SD (standard deviation) of three replicates.
