“…In the shell of bivalve, mainly made of calcium carbonate (CaCO 3 ), calcite and aragonite are the prevalent forms, but there are also highly unstable amorphous phases (ACC) 3 . These polymorphic transitions of CaCO 3 are classified as of second order, like the temperature of glass transition (Tg) of amorphous materials, and would represent an intermediate case between transformations of the displacive type (of the type beta quartz -alpha quartz) and order-disorder transitions (amorphization) 4 . The shells act as skeletons for supporting the soft parts of the molluscs' body, offer mechanical protection against predators and, in terrestrial species, keep abrasive materials (earth and sand) out of the mantle cavity 5 .…”

Applying the theories of Materials Science and Engineering to describe the composition and hierarchy of microstructures that comprise biological systems could help the search for new materials and results in a deeper insight into evolutionary processes. The layered microstructure that makes up the freshwater bivalve Limnoperna fortunei shell, an invasive specie in Brazil, was investigated utilizing SEM and AFM for the determination of the morphology and organization of the layers; and XRD was used to determine the crystalline phases of the calcium carbonate (CaCO 3 ) present in the shell. The presence of the polymorphs calcite and aragonite were confirmed and the calcite is present only on the external side of the shell. The shell of L. fortunei is composed of two layers of aragonite with distinct microstructures (the aragonite prismatic layer and the aragonite sheet nacreous layer) and the periostracum (a protein layer that covers and protects the ceramic part of the shell). A new morphology of the calcite layer was found, below the periostracum, without defined form, albeit crystalline.

“…Since then, the biomimetic study of calcium carbonate crystallization on ordered substrates has attracted attention. The later crystallizations of calcium carbonate on Langmuir films or self-assembled monolayers (SAM) provide many good examples of the template effect on oriented crystallization [69,[104][105][106][107]. The template effect usually refers to the geometric or stereochemical match between a final crystal face and an organic matrix.…”

Amorphous Phase Mediated Crystallization: Fundamentals of Biomineralization

Many biomineralization systems start from transient amorphous precursor phases, but the exact crystallization pathways and mechanisms remain largely unknown. The study of a well-defined biomimetic crystallization system is key for elucidating the possible mechanisms of biomineralization and monitoring the detailed crystallization pathways. In this review, we focus on amorphous phase mediated crystallization (APMC) pathways and their crystallization mechanisms in bio-and biomimetic-mineralization systems. The fundamental questions of biomineralization as well as the advantages and limitations of biomimetic model systems are discussed. This review could provide a full landscape of APMC systems for biomineralization and inspire new experiments aimed at some unresolved issues for understanding biomineralization.

“…Of all the minerals formed by organisms, calcium carbonate (CaCO 3 ) is well known not only because it is widely distributed in nature, but also because it is a kind of typical mineral to reveal the biomineralization mechanism which is mystical to the curious people. On the other hand, understanding the design strategy behind the mineral will hold great promise for the future development of biological, chemical and materials sciences [3][4][5][6][7][8][9].…”

Mollusk biomineralization is an elaborate process in which cells, organic macromolecules, and calcium carbonate crystals are actively involved.Macromolecules (mainly are proteins and polysaccharide) act as a key role in regulating and limiting the size, orientation, polymorph and texture of inorganic phase. In this work, we focused on the inter-prismatic matrix of mollusk shell combining scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM) analytical techniques with CaCO 3 recrystallization experiment to characterize its structure and effects on crystal formation. Our results show that the inter-prismatic matrix is not a sort of pure polymer, calcite nano-crystals are also located inside the inter-prismatic matrix. Interestingly, it seems that these nanocrystals have a preferred orientation, which means the inter-prismatic matrix do impose effect on the crystal formation. In vitro re-crystallization experiment using partially dissolved prismatic fragment as template indicates that the (104) faces of CaCO 3 micro-crystals are closely associated with the walls of inter-prismatic matrix. Furthermore, a possible growth mechanism of mollusk shell prismatic layer was proposed.Key Words: Biomineralization, Mollusk shell, Inter-prismatic matrix, Calcite, Dissolution Citation: D.
