Morphogenesis of Aragonite Biomineral Structures by the Nonclassical Colloidal Crystal Growth Mechanism Revisited on the Nanoscale: The Noah's Ark Shell (<i>Arca noae</i>, L.) Case Study.

ABSTRACT: Characterization and formation of the biomineral aragonite structures of the Noah's Ark shell (Arca noae L.,1758) were studied from structural, morphogenetic, and biochemical points of view. Structural and morphological features were examined using X-ray diffraction, field-emission scanning electron microscopy, and atomic force microscopy, while thermal properties were determined by thermogravimetric and differential thermal analyses. Proteins from the soluble organic matrix (SOM) were analyzed by Edman degradation. The results showed that the Noah's Ark shell exhibits several distinct biomineral structures characterized by complex morphologies and different forms of aragonite. The inner shell of the Ark is characterized by a combination of nanogranular surfaces and micron-sized, id
