“…Similar results were observed by Hu and co-workers [ 13 ] where this type of morphology was referred to as a ‘stack-like’ structure that consists of many thin sheets. Zheng and co-workers [ 1 ] obtained calcium carbonate structures in the presence of egg white, and these structures consisted of many thin sheets. Based on these results, the multilayered structure of the organic/inorganic matrix in egg shells can result from the presence of ovalbumin in avian organisms.…”

“…Calcium carbonate is an important biogenic mineral used by nature as an inorganic component in tissues and exoskeletons of many mineralizing organisms [ 1 , 2 , 3 ]. These biocompatible inorganic microparticles have become an active area of research due to their exquisite nanostructures, superior mechanical properties, and unique biological functions, such as support, protection, sensing, storage, and homeostasis [ 4 , 5 ].…”

Calcium carbonate is an important component in exoskeletons of many organisms. The synthesis of calcium carbonate was performed by mixing dimethyl carbonate and an aqueous solution of calcium chloride dihydrate. The precipitation product was characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) measurements. In addition, the turbidity of the reaction solution was acquired to monitor the kinetics of the calcium carbonate structure’s growth in the investigated system. In this study, samples of CaCO3 particles obtained with individual proteins, such as ovalbumin, lysozyme, and a mixture of the proteins, were characterized and compared with a control sample, i.e., synthesized without proteins. The obtained data indicated that the addition of ovalbumin to the reaction changed the morphology of crystals from rhombohedral to ‘stack-like’ structures. Lysozyme, however, did not affect the morphology of calcium carbonate, yet the presence of the protein mixture led to the creation of more complex composites in which the calcium carbonate crystals were constructed in protein matrices formed by the ovalbumin-lysozyme interaction. It was also observed that in the protein mixture, ovalbumin has a major influence on the CaCO3 formation through a strong interaction with calcium ions, which leads to the coalescence and creation of a steric barrier reducing particle growth. The authors proposed a mechanism of calcium carbonate grain growth in the presence of both proteins, taking into account the interaction of calcium ions with the protein.

“…The changes in zeta potential value were also observed by other researchers using polypeptides, fulvic acid or stearic acid [ 18 , 19 ]. From previous data in the literature, it is known that biomolecules can adsorb on solid faces formed as a result of the crystallization process and change the interfacial energy [ 20 , 21 ]. This may explain the decrease in particle size in the presence of surfactin, as shown in Figure S1 and Table 1 .…”

This study presents a new, simple way to obtain mesoporous calcite structures via a green method using an eco-friendly surface-active compound, surfactin, as a controlling agent. The effects of synthesis time and surfactin concentration were investigated. The obtained structures were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) coupled with gas mass spectrometry (QMS) analysis. The experimental data showed that surfactin molecules significantly changed the morphology of the calcite crystals, roughening and deforming the surface and creating a greater specific surface area, even at low biosurfactant concentrations (10 ppm). The size of the crystals was reduced, and the zeta potential value of calcium carbonate was more negative when more biosurfactant was added. The XRD data revealed that the biomolecules were incorporated into the crystals and slowed the transformation of vaterite into calcite. It has been shown that as long as vaterite is present in the medium, the calcite surface will be less deformed. The strong influence of surfactin molecules on the crystal growth of calcium carbonate was due to the interaction of surfactin molecules with free calcium ions in the solution as well as the biomolecules adsorption at the formed crystal surface. The role of micelles in crystal growth was examined, and the mechanism of mesoporous calcium carbonate formation was presented.

“…Egg white is a natural biological fluid, which has been found to be able to affect the crystallization of CaCO 3 . It results in different structures such as wool sphere‐like and brick‐and‐mortar ordered structure . Additionally, the anionic proteoglycans in eggshell and egg membrane also influence the mineralization process and the final crystal structure.…”

Egg substrates, including eggshell, egg membranes, and egg white, exert a significant influence on CaCO 3 biomineralization. CaCO 3 crystallization at different temperatures, concentrations, and with various egg substrates was systematically investigated via rapidly mixing solution method. The crystals were determined by scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. As the CaCl 2 concentration increased, the CaCO 3 crystal form gradually changed from calcite to vaterite. Under rising temperature, the single-hole vaterite and besom-like aragonite were formed on the raw and boiled egg white substrate, respectively. The effects of electric field on CaCO 3 crystallization were also explored. The findings may offer a novel approach to CaCO 3 synthesis.
