Monolayer mesoscale self-assembly of hexagonal microplatelets at water-air interface of droplets and real-time dynamical observation of the self-assembling process driven by mechanical agitation.
(a) Experimental setup used for self-assembly, including an inverted plastic Petri dish and an optical microscope with inverted lens. (b) Three droplets of microplatelets suspension on the inner surface of a plastic Petri dish. (c) Schematic illustration of self-assembly of microplatelets at water-air interface of the droplets hanging at the bottom surface of the plastic Petri dish for inverted lens to observe. (d) Optical image frames of self-assembling process, showing the microplatelets gradually formed an integrated and well-ordered pattern (scale bar is 200 μm).
