“…Moreover, although there is still debate on whether biomimetic mineralization is mediated by a stereochemical match of acid head groups and the inorganic phase, or solely by the presence of polar or charged functional groups, [11,16,17] many research results have shown that selectivity for certain crystal faces appears to be highly dependent on the secondary structure of the macromolecule additives.

IntroductionInspired by the exquisite and highly functional architectures of biominerals, organic templates and/or additives with complex functionalization patterns are universally employed to control the nucleation, growth, and alignment of inorganic crystals for the biomimetic synthesis of inorganic materials with specific size, shape, morphology, and structure. [1][2][3][4] Calcium carbonate (CaCO 3 ) is an attractive model mineral for its abundance in nature and also for its important industrial applications. CaCO 3 has three anhydrous crystalline polymorphs, i.e., vaterite, aragonite, and calcite in order of increasing stability and decreasing solubility, and it is often found that less stable forms are stabilized kinetically. Biomimetic synthesis of CaCO 3 under the influence of organic templates and/or additives has been intensively investigated in recent years as reiewed recently. [5,6] Langmuir monolayers and Full PaperHyperbranched aliphatic polyesters functionalized with carboxylic or sulfonic acid groups have been synthesized and employed as crystallization modifiers for calcium carbonate. The functionalized polyesters exhibit remarkable polymorph selectivity and morphology control. Stable spherical vaterite particles of diameter less than 10 mm with narrow size distribution were easy to produce on a large scale. With an increase in the concentration and monomer/ core ratio of the polyester, the vaterite content increases accordingly with promoted morphology control to monodisperse spheres. The CaCO 3 concentration and the initial pH can also influence the morphology and polymorphism of the produced calcium carbonate. Under certain conditions, well-defined core-shell structured vaterite spheres are obtained with obvious radial organization by nano-aggregation of about 70 AE 10 nm crystallites, which may mediate and combine the nano-aggregation and crystal growth formation mechanism of vaterite polymorph.

“…In recent years, the manifestation of hydrogel-organic matrix in bio mineralization has gained much attention for the development of novel bio-inspired polymeric material for bone tissue engineering or other biomedical applications [4]. Grassmann et al [5][6][7] prepared CaCO 3, in polyacrylamide hydrogels, sulfonic acid based hydrogels and carboxylate groups bearing poly-acrylamide hydrogels, respectively and mostly studied about morphologies of calcites because in gel matrix, the network structure of hydrogel exert different influences on the crystallization of minerals [1].…”

Abstract. Mineralization of calcium carbonate (CaCO 3 ) in hydrogel matrix is one of the most interesting topics of research by material scientists for the development of bio-inspired polymeric biomaterial for biomedical applications especially for bone tissue regeneration. As per our knowledge there was no work reported about rheological properties of CaCO 3 mineralized hydrogel though some works have done on mineralization of CaCO 3 in various gel membranes, and also it was reported about the viscoelastic properties of Agarose, Cellulose, PVA and PVP-CMC hydrogels. This paper mainly focuses about the effect of strain on viscoelastic properties of fresh, swelled and mineralized (CaCO 3 ) PVP-CMC hydrogel. All these three types of hydrogel sustain (or keep) strictly the elastic properties when low strain (1%) is applied, but at higher strain (10%) the viscoelastic moduli (G' and G") show significant change, and the nature of these materials turned from elastic to viscous.

“…Therefore, an artificial hydrogel has been used as an excellent crystallization medium in previous biomimetic studies [6][7][8][9]. Estroff et al [10][11][12] suggested that the gel can effectively reduce the ion activities and diffusion rates so that the crystallization process in the gel is totally different from that occurring in aqueous solution.…”

Biological mineral generation via an amorphous precursor is a topic of great current interest. Various factors such as the temperature, solution composition and presence of organic molecules can influence this important inorganic process. Here we demonstrate that this mineral transformation can actually readily be regulated by solution viscosity, a fundamental but often overlooked property. In our experiment, amorphous calcium carbonate (ACC), a key model compound in biomimetic mineralization studies, is synthesized and dispersed into inert dispersants with different viscosities and the crystallization process is examined by using FT-IR spectroscopy and XRD. It is found that the inhibition of the transformation of ACC becomes more significant with increasing fluid viscosity. This phenomenon can be explained by the differences in ion diffusion in different media. Furthermore, the resulting crystals always have different morphologies and size distributions although they all have the calcite structure. This study implies that the importance of the fluid medium cannot be ignored in building a complete understanding of biological control of biomimetic crystallizations. mineralization, amorphous calcium carbonate, transformation, viscosity
