Application
Calcium Carbonate standard reference material (SRM) is primarily intended for calibrating, validating, and standardizing analytical methods used in clinical analysis for determining calcium (Ca) and carbonate.

Application

• Unlocking the potential of amorphous calcium carbonate: A star ascending in the realm of biomedical application.: This review explores the diverse biomedical applications of high-purity amorphous calcium carbonate, emphasizing its utility in drug delivery systems and tissue engineering. The study underscores its significance in pharmaceutical formulations and as a buffer agent in various biomedical contexts (Liu et al., 2024).


• Immunohistochemical and ultrastructural characterization of the inner ear epithelial cells of splitnose rockfish (Sebastes diploproa).: Calcium carbonate is crucial in the formation and function of otoliths in fish. This study provides detailed insights into the cellular mechanisms involving calcium carbonate in the inner ear of fish, which is essential for understanding balance and hearing functions (Kwan et al., 2024).


• Calcium carbonate polymorph selection in fish otoliths: A key role of phosphorylation of Starmaker-like protein.: The research focuses on the selection of calcium carbonate polymorphs in fish otoliths, driven by protein phosphorylation. The study′s findings have significant implications for the design of biomimetic materials and the study of mineralization processes in biological systems (Kalka et al., 2024).


• Biomineralization of mantis shrimp dactyl club following molting: Apatite formation and brominated organic components.: This study investigates the biomineralization process in mantis shrimp, emphasizing the role of calcium carbonate in forming their dactyl clubs. The insights gained are crucial for developing advanced materials inspired by biological mineralization processes (Chua et al., 2023).

Features and Benefits

• The certified mass fraction values for elements are provided on a dry-mass basis and values are metrologically traceable to the SI unit of mass, expressed as a percentage.
