In this study, synthesis of biomimetic hierarchical architectures of inorganic materials was investigated for application of the specific nanostructure to various functional materials including electrodes, catalysts, and bioactive devices. The hierarchical crystals of oxides and phosphates, such as manganese oxides, tin oxides, titanium dioxide, and hydroxyapatite, were successfully prepared through crystal growth with specific interaction between metal ions and organic molecules in aqueous solution systems. These materials were found to exhibit excellent performance as electrodes of lithium-ion secondary battery, reaction-selective photocatalysts, and cell-selective scaffolds. These results indicate that the hierarchical structures consisting of tailored nanocrystals have high potential in a wide variety of application fields.
