Hierarchical structures can be found in nature from the macroscopic level to the microscopic level. Biomaterials are selectively self-organized from molecular- to macrolength scales, with organized units of subassemblies that are generated to serve biological purposes. Inspired by the complexity of biomaterials, research has been initiated to mimic biomineralization processes and chemically produce hierarchical structures. This chapter is focused on a new methodology to generate hierarchical materials as novel sorbents for separation of metal ions via hierarchical imprinting synthesis.
