In this paper, we demonstrated a unique and simple method for fabricating colloidal particles of complex
structures using oil-in-water emulsion droplets as confined geometries. A variety of structural motifs
were produced using binary colloids of microspheres of polystyrene (PS) or silica and nanosized particles
as the second component. When PS or silica microspheres and PS macromolecules were dispersed in
oil-in-water emulsion droplets, particles with well-coordinated patches were obtained because the PS
macromolecules partially covered the microsphere clusters. When silica or gold nanoparticles were
dispersed together with the PS microspheres in oil-in-water emulsion droplets instead of PS macromolecules, composite particles with patches were obtained. In this case, silica or gold shell structures with
well-coordinated windows were produced by selectively removing the large PS microspheres from the
organic−inorganic composite clusters.
