Colloidal crystal templating is a simple, highly versatile synthetic technique for creating periodic structures with nanometer-to-submicrometer features in three dimensions. It is used to synthesize highly ordered porous materials with a wide range of pore sizes, morphologies, and compositions. The inverse opal products are being investigated by scientists around the world for a variety of applications, where they can provide features and functionalities that are either difficult to obtain by other methods or (in the case of 3D photonic crystals) much less expensive than alternative techniques. As the field of colloidal crystal templating continues to grow, more unique materials and applications are sure to be developed.
