Apatite Biominerals

Abstract: Calcium phosphate apatites offer outstanding biological adaptability that can be attributed to their specific physico-chemical and structural properties. The aim of this review is to summarize and discuss the specific characteristics of calcium phosphate apatite biominerals in vertebrate hard tissues (bone, dentine and enamel). Firstly, the structural, elemental and chemical compositions of apatite biominerals will be summarized, followed by the presentation of the actual conception of the fine structure of sy… Show more

“…Materials that exhibit a high net negative surface charge, such as high surface area silica and Si 3 N 4 , have also demonstrated the ability to induce heterogeneous HAp precipitation from SBF due to elevated concentrations of Ca 2+ ions within the counterion clouds that shroud their highly‐charged surfaces in solution. Additionally, the presence of the N‐apatite phase within the SiYAlON glaze, which is isostructural to native HAp, likely further facilitates HAp precipitation due to a reduced energy barrier for heterogeneous nucleation . Finally, chemical interactions between the extracellular medium, biomaterial surface, and osteoprogenitor cells can influence osteoblast differentiation and metabolism, production of extracellular collagen, cell motility, production of matrix vesicles, and expression of molecules that regulate the bone remodeling process .…”

“…Основой неорганической составляю-щей эмали и дентина зубов является нестехиометриче-ский гидроксиапатит кальция (ГАП) с большим числом изоморфных замещений в структуре [11,12], который имеет собственный спектр ФЛ. При этом необходимо отметить, что тип дефекта в структуре гидроксиапатита кальция может определять положение максимума люми-несценции [13].…”

“…A number of XRD studies on bone crystallinity and crystallite size have been carried, and the differences in crystal size and the FWHM of bone were repeatedly observed 20,[35][36][37][38][39][40][41][42][43] . As for the FWHM, this study disclosed three new findings: i) the FWHM values showed a wide deviation range, ii) a small FWHM value not reported previously, iii) the variation of the FWHM values in the closely neighbouring regions of one small bone mass.…”
