“…Controlled mineralization of CaCO 3 has been actively investigated [ 29 ] and further research is still needed. Most studies to date have dealt with the nucleation and crystallization of particles in solution, but comparatively few reports can be found on the formation of carbonate coatings [ 30 ]. The development of the calcium carbonate surface protection method on Mg was carried out in a preliminary phase by studying reactions in carbonated water from the native corrosion product of Mg, i.e., Mg hydroxide, brucite, and Mg(OH) 2 , to determine the formation of appropriate interfaces and of the chemical bond, by conversion from the hydroxide to the interface material of the coatings.…”

Mg is a material of choice for biodegradable implants. The main challenge for using Mg in temporary implants is to provide protective surfaces that mitigate its rapid degradation in biological fluids and also confer sufficient cytocompatibility and bacterial resistance to Mg-coated surfaces. Even though carbonate mineralization is the most important source of biominerals, such as the skeletons and shells of many marine organisms, there has been little success in the controlled growth of carbonate layers by synthetic processes. We present here the formation mechanism, antibacterial activity, and cell viability of magnesian calcite biomimetic coatings grown on biodegradable Mg via a green, one-step route. Cell compatibility assessment showed cell viability higher than 80% after 72 h using fibroblast cells (NCTC, clone L929) and higher than 60% after 72 h using human osteoblast-like cells (SaOS-2); the cells displayed a normal appearance and a density similar to the control sample. Antimicrobial potential evaluation against both Gram-positive (Staphylococcus aureus (ATCC 25923)) and Gram-negative (Pseudomonas aeruginosa (ATCC 27853)) strains demonstrated that the coated samples significantly inhibited bacterial adhesion and biofilm formation compared to the untreated control. Calcite coatings grown on biodegradable Mg by a single coating process showed the necessary properties of cell compatibility and bacterial resistance for application in surface-modified Mg biomaterials for temporary implants.

“…The single crystals of fibrous calcite and tablet aragonite show a similar EY adsorption capability for surface unit, 0.20 and 0.19 mg/m 2 , respectively. This may seem unexpected since calcite and aragonite have different crystal structures and expose different crystalline faces . However, the proposed surface structural re-organization, which produces surface hydroxyl groups, can be considered to justify this similarity.…”

“…This may seem unexpected since calcite and aragonite have different crystal structures and expose different crystalline faces. 53 However, the proposed surface structural re-organization, which produces surface hydroxyl groups, 52 can be considered to justify this similarity. The adsorption of BM, which occurs via no site-specific interactions (i.e., Freundlich isotherm), was slightly higher on aragonite tablets (0.052 mg/m 2 ) than on fibrous calcite (0.032 mg/m 2 ).…”

Control over the shape and morphology of single crystals is a theme of great interest in fundamental science and for technological application. Many synthetic strategies to achieve this goal are inspired by biomineralization processes. Indeed, organisms are able to produce crystals with high fidelity in shape and morphology utilizing macromolecules that act as modifiers. An alternative strategy can be the recovery of crystals from biomineralization products, in this case, seashells. In particular, waste mussel shells from aquaculture are considered. They are mainly built up of single crystals of calcite fibers and aragonite tablets forming an outer and an inner layer, respectively. A simple mechanochemical treatment has been developed to separate and recover these two typologies of single crystals. The characterization of these single crystals showed peculiar properties with respect to the calcium carbonate from quarry or synthesis. We exploited these biomaterials in the water remediation field using them as substrate adsorbing dyes. We found that these substrates show a high capability of adsorption for anionic dye, such as Eosin Y, but a low capability of adsorption for cationic dyes, such as Blue Methylene. The adsorption was reversible at pH 5.6. This application represents just an example of the potential use of these biogenic single crystals. We also envision potential applications as reinforcing fillers and optical devices.

“…The nacreous layer of mollusks comprises alternating layers of brittle inorganic calcium carbonate platelets and biopolymers, and it exhibits remarkably high toughness and resilience. [9][10][11] The outstanding merits of nacre can be attributed to the hierarchical arrangement of its so and hard constituents that shape a brick-and-mortar structure. 7,12 The nacre-inspired design principle is to arrange the hard, reinforcing platelets and energy-dissipating so polymers into ordered structures.…”

Calcium carbonate: controlled synthesis, surface functionalization, and nanostructured materials

Abstract: Various new strategies have been recently developed to produce CaCO3 micro-/nanoparticles with controlled size, morphology, polymorphism and crystallinity, which are then surface modified, functionalized and hierarchically assembled to yield medical, environmental, and energy materials.
