Sažetak
Marine mollusks produce complex aragonite biomineral forms that have unique structural and morphological properties in comparison with abiotic analogues, especially because they are formed at ambient pressure and temperature. This research studies the formation, structural and morphological properties of aragonite biomineral occurring in Noah’s ark (Arca noae), noble fan mussel (Pinna nobilis) and common cuttlefish (Sepia officinalis). Morphology of aragonite in these organisms was examined by field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM). Results obtained showed that aragonite structures are composed of well defined and uniform nanoparticle building blocks formed through the oriented aggregation processes of the initially formed nanosized aragonite crystallites. These findings confirm the hypothesis that the non-classical nanoscale aggregation route is a common mechanism in the formation of the hierarchically organized aragonite forms in marine organisms.
