A fundamental concept in the study of biomineralization concerns the molecular recognition of inorganic materials at organized organic macromolecular substrates1. Here we investigate this concept through the use of stearic acid monolayers in the controlled crystallization of CaCO3 from supersaturated solutions. Whereas crystallization in the absence of a monolayer results in rhombohedral calcite crystals, the presence of an organized monolayer gives rise to oriented vaterite formation. The… CONTINUE READING
