Abstract

Two-dimensional (2D) non-close-packing arrays were fabricated by dip-coating hydrogel spheres unloaded and loaded with CaCO₃ formed via in situ biomineralization. The separation distance between the particles can be well tuned by the dip-coating speed and the concentration of the gel spheres. The resultant 2D non-close-packing arrays can be used as templates to direct the self-assembly of silica colloidal spheres for formation of binary colloidal crystals with different patterns. The resulting binary structures may be manipulated by the surface wettability. Besides, they can be utilized as masks to generate functional patterned substrates.
