Modification of Surfaces with Vaterite CaCO3 Particles

Abstract

Former studies have demonstrated a strong interest toward the crystallization of CaCO3 polymorphs in solution. Nowadays, CaCO3 crystallization on solid surfaces is extensively being studied using biomolecules as substrates for the control of the growth aiming at various applications of CaCO3. Calcium carbonate exists in an amorphous state, as three anhydrous polymorphs (aragonite, calcite and vaterite), and as two hydrated polymorphs (monohydrocalcite and ikaite). The vaterite polymorph is considered as one of the most attractive forms due to its large surface area, biocompatibility, mesoporous nature, and other features. Based on physical or chemical immobilization approaches, vaterite can be grown directly on solid surfaces using various (bio)molecules, including synthetic polymers, biomacromolecules such as proteins and peptides, carbohydrates, fibers, extracellular matrix components, and even biological cells such as bacteria. Herein, the progress on the modification of solid surfaces by vaterite CaCO3 crystals is reviewed, focusing on main findings and the mechanism of vaterite growth initiated by various substances mentioned above, as well as the discussion of the applications of such modified surfaces.

Tunable Nanomaterials of Intracellular Crystallization for In Situ Biolabeling and Biomedical Imaging

“…67−70 The multidimensional structure of proteins is the site of nucleation for biomineralization of inorganic nanomaterials, or reduced biomolecules provide the chemical energy for biochemical synthesis and ultimately the formation of nanomaterials with specific functions. 71,72 This hints that the biosynthesis system may be an outstanding reactor to synthesize nanoprobes that can be used for chemical biomedical imaging.…”

Physicochemical Understanding of Biomineralization by Molecular Vibrational Spectroscopy: From Mechanism to Nature

“…Mostly as amorphous calcium carbonate (ACC), aragonite, and calcite occur in the shells of crustaceans and the teeth of sea urchins. [60,61,168] , a portion of carbonate is also present in vertebrate enamel and bone. During the maturation of hydroxyapatite, carbonate ions replace the hydroxyl or phosphate in it, thus changing the stability and solubility of the mineral phase.…”

Identification and characterization of calcite producing bacteria isolated from soils in West Java, Indonesia

“…In most cases, the microbial metabolic products react with the surrounding environment and form mineral precipitation (Seifan 2016). Calcium carbonate (CaCO3) is one of the most common minerals widespread on earth with various polymorphs and calcite is the most thermodynamically stable polymorph of CaCO3 (Zafar et al 2022). Numerous species of bacteria from soil and various extreme environments have been reported for their ability to precipitate calcium carbonate by creating an alkaline condition through different physiological activities (Elmanama and Alhour 2013).…”
