Aggregates of colloid particles has been always a focus in many researchers’ eyes due to their unique properties of optics, amphipathy, anisotropism and magnetism. Controlling morphology and structure of these aggregates at sub-micrometer and micrometer scales was also an extreme aspiration for several researchers. Up to now, there have been a lot of smart techniques for preparation of colloidal aggregates with various structures and morphologies, such as, micropipette injection, soft microfluidic device and spray drying.<br/>In this present work, a variety of aggregates with different structures and morphologies were fabricated by self-assembly of silica colloidal particles confined in water-in-oil droplets. The Water-in-oil droplets containing monodisperse or bidisperse silica particles were produced by ultrasonic dispersion of mixture of silica sol and different organic solvents. Controlling of morphology and structure was simple and facile in this method.
