“…These examples emphasize that nanophase materials deserve more attention in improving orthopedic implant failure rates. However, to reduce surface energy, all nano-sized materials tend to agglomerate and, to avoid self-aggregation of calcium orthophosphate nano-sized particles [195][196][197][198], special precautions might be necessary [54,60,120,[199][200][201][202].…”

Nano-sized particles and crystals play an important role in the formation of calcified tissues of various animals. For example, nano-sized and nanocrystalline calcium orthophosphates in the form of apatites of biological origin represent the basic inorganic building blocks of bones and teeth of mammals. Namely, according the recent developments in biomineralization, tens to hundreds nanodimensional crystals of a biological apatite are self-assembled into these complex structures. This process occurs under a strict control by bioorganic matrixes. Furthermore, both a greater viability and a better proliferation of various types of cells have been detected on smaller crystals of calcium orthophosphates. Thus, the nano-sized and nanocrystalline forms of calcium orthophosphates have a great potential to revolutionize the hard tissue-engineering field, starting from bone repair and augmentation to controlled drug delivery systems. This review reports on current state of the art and recent developments on the subject, starting from synthesis and characterization to biomedical and clinical applications. Furthermore, the review also discusses possible directions for future research and development.

“…The phosphate supports, namely, Mg 3 (PO 4 ) 2 (MgP), hydroxyapatite (HA) -Ca 10 (PO 4 ) 6 (OH) 2 , AlPO 4 , AlPO 4 (AlP), TiOHPO 4 (TiP), and Zr 3 (PO 4 ) 4 (ZrP) were synthesized according to reported methods [12][13][14][15] by precipitation from soluble salts of the corresponding metals or from the freshly-prepared hydroxide (in the case of magnesium phosphate) by adding phosphoric acid or ammonium hydrophosphate (in the synthesis of hydroxyapatite) maintaining the required pH with subsequent rinsing of the precipitates with water, drying, and heat treatment. In the preparation of mesoporous aluminum phosphate (AlP M ), 2% aqueous cetylpyridinium chloride was added in the precipitation step.…”

A series of heterogeneous composite photocatalysts was prepared by the deposition of titanium dioxide on porous magnesium phosphate, calcium phosphate, titanium phosphate, zirconium phosphate, and aluminum phosphate supports. The activities of these photocatalysts were compared in the photodecomposition of Rhodamine C dye by the action of UV irradiation. The best functional characteristics were found for the photocatalysts on the magnesium phosphate support treated at 750°C. The use of the photocatalysts on phosphate supports was found to hold promise in photocatalytic water purification.

“…Нанокристаллический ГА обладает повышенной способностью адсорбировать белки, необходимые для жизнедеятельности клеток, и избирательностью по отношению к функциям клеток, образующих костную и фиброзную ткань [5]. В доклинических испытаниях показано, что наноструктурный ГА обладает большей способностью стимулировать репаративный остеогенез, чем его поликристаллический аналог [6], что может свидетельствовать о его остеоиндуктивных свойствах [3].…”
