Fig. S – I: Comparison of diameters of the water-in-oil droplets directly
measured from the still images and calculated from droplet volumes
which are estimated by dividing the water flow rate by frequency count of
the droplet generation (0.83µl/min ≤ Qw ≤ 8.33µl/min and
1.66µl/min ≤ Qo ≤ 83.3µl/min).
