Monodisperse spherical colloids such as polymer latexes and silica suspensions serve as model systems for practical colloidal materials because of their unique response to external electromagnetic and flow fields. In addition, their self-organization with three-dimensional (3D) periodicity on the scale of optical wavelengths has received much attention as a promising route for 3D photonic band gap materials. Recently, various organic or inorganic monodisperse colloidal dispersions have been prepared with particles of non-spherical shapes such as ellipsoids, dumbbells, and hollow spheres. Their complexity may make it possible to fabricate novel photonic band gap materials as well as to model real colloids with irregular structures. Another approach to preparing such structured particles is to use assemblies of spherical colloids. In this presentation, we report on soft-lithography-based microfluidic approaches for the fabrication of micron-sized 3D colloidal assemblies with narrow size distribution and internal ordered structure of monodisperse latex.
