Calcium carbonate (CaCO3), one of the most abundant biominerals on Earth, exists in three main crystalline polymorphs: aragonite, calcite, and vaterite. These polymorphs have a wide range of naturally occurring crystal habits, and they are often found assembled into hierarchical structures that result in a variety of intriguing properties in organisms. As the process of biomineral formation (which involves additives such as amphiphiles, proteins, nucleic acids, a structure directing insoluble matrix, and the action of specialized cells) is too complex to be understood at the molecular level, one must resort to simplified models which allow an understanding of certain key factors of the biomineralization process. Two such models-Langmuir monolayers and self-assembled monolayers (SAMs)-are reviewed in this chapter. Mineral formation at organic surfaces in natural systems is affected by physical, chemical, and molecular interactions, and molecular interactions at the organic aqueous interface, which can be controlled with molecular precision in Langmuir layers and SAMs. Phase selection and crystal orientation (i.e., the nucleating plane) of the growing crystal are determined by: (i) surface polarity; (ii) surface ordering/roughness; (iii) surface geometry/symmetry; and (iv) head group orientation due to even or odd chains. The concepts of template-induced crystallization on SAMs, and the use of polymer additives, can finally be combined to a new strategy where, through the cooperative interaction of a matrix involved in the nucleation process, an additive in solution and the dissolved ions, hierarchically ordered mineral structures are formed. © 2007 WILEY-VCH Verlag GmbH & Co.
