Fig. 3. (a) Schematic illustration of the observation of evaporation of the sessile droplets. (b) Optical microscopy images of EA(0)710 and PS microspheres at the air/water interface at the center of each droplet on the glass substrate during evaporation. The initial concentration of particles in the droplets was 0.05 wt% (EA(0)710; Movie S1, ESI†) or 0.08 wt% (PS; Movie S2†). (c) Normalized amount of adsorbed microspheres, NN, as a function of TN.
