Hierarchical structures of self-assembled hybrid calcium carbonate: nucleation kinetic studies on biomineralization

Abstract

A novel CaCO₃ hybrid material with a well-ordered hierarchical structure was synthesized under the effects of phosvitin. Kinetic experiments demonstrate that phosvitin suppresses the supersaturation-driven interfacial structure mismatch between CaCO₃ crystallite and substrate, and promotes the formation of oriented CaCO₃ nanocrystallite assemblies at low supersaturations.
