Results and Statistics of the generated microdroplets. (a) Optical bright-field micrographs of droplets around 25 μm in diameter are produced. (b) Produces a particle size uniformity distribution of microdroplets with a diameter of about 25 μm. (c) Produces an optical bright-field micrograph of a droplet with a diameter of about 50 μm. (d) Produces a particle size uniformity distribution of microdroplets with a diameter of about 50 μm. The scale bar is 50 μm. The above experiments used droplet-specific oils (2% surfactant in HFE 7500) to prevent intermiscibility of the printed droplets, and picolitre-scale droplets were printed directly into oils packed in microtiter plates during the experiments.
