Figure 1. Generation and properties of DE droplets.

Figure 1

(a,b) Formation of w/o and w/o/w emulsions in two flow-focusing devices. (c) Schematic diagram showing how DE droplets are generated and spheroids are formed. Cells encapsulated in DE droplets assemble to form a single spheroid, which can be subsequently released with or without microgel encapsulation. (d) The appearance of DE droplets generated in device with 100 μm channel width after collection. The red arrow indicates an empty oil droplet generated as side product. (e) Diffusion curve of different dyes encapsulated in DE droplets. Molecular weight (MW) and partition coefficient (PC) of the dyes are provided in the legend. (f) Size of core of DE droplets controlled by fixing inner aqueous phase flow rate at 2 μL/min and altering oil phase flow rate (n ≥ 30). Figure 1C used with permission from Siying Ma.
