Sorting and purification of PFC liquid droplet emulsions. (A) A polydisperse population of PFC droplets produced by high-speed shaking. Size bar, 150 μm. (B) Distribution of PFC droplets in the separation channel of μ-SOHSA. Larger droplets are separated from a fluorescent stream of smaller droplets and are positioned in the lower region. Size bar, 500 μm. (C) This separation successfully isolates target droplets (< 6 μm) into the upper collector, which can be optically confirmed by the micrograph of smaller droplets shown in (D). (E) & (F) Larger droplets are driven selectively into the lower collector and removed from the original population. Size bar, 150 μm.
