Uniform spherical colloidal assemblies of closely packed monodisperse colloidal particles have been prepared by injecting an aqueous suspension of polymer spheres into a surfactant‐laden oil phase through a micropipette. The size of these assemblies can be controlled by varying the injection pressure or particle concentration. The Figure shows 6.3 μm diameter assemblies composed of 230 nm particles.
