In nature, biological organisms produce mineralized tissues such as bone,teeth, diatoms, and shells. Biomineralization is the sophisticated process ofproduction of these inorganic minerals by living organisms. Construction oforganic-inorganic hybrid materials with controlled mineralization analogousto those produced by nature has recently received much attention because itcan aid in understanding the mechanisms of the biomineralization processand development of biomimetic materials processing. The biomineralizationprocesses use aqueous solutions at temperatures below 100℃ and no toxicintermediates are produced in these systems. From a serious global envi-ronmental problem point of view, the development of processes inspired y
biomineralization would offer valuable insights into material science and engi-neering to reduce energy consumption and environmental impact. One of themost challenging scientific problems is to gain greater insight into the molec-ular interactions occurring at the interface between the inorganic mineraland the macromolecular organic matrix. Model systems are often regarded asa straight-forward experimental approach toward biomimetic crystallization.Hierarchical architectures consisting of small building blocks o finorganic crys-tals are often found in biominerals. Studies of nanocrystal self-organization insolution systems would also be helpful for understanding biomineralization. |
