Single Mobile Micro Droplet-Particle Pairs Spatially Captured by Macro Host Droplets on a Superhydrophobic Surface

Figure 4

(a) Optical image of condensate which has previously self-propelled onto the surface of the host drop (see also Movie S6). The image of the condensate was acquired after movement into a clear field of view (i.e., in focus). (b): before and after images of a single mobile droplet impacting onto the host drop and adhering to a single particle residing on the host drop (see also Movie S7).
