“…Terbium (Tb) has attracted extensive attention due to its multiple potential application in biomedical field when combined with HA, Tb being one of the most luminescent rare-earth biological probes due to its excellent emission feature with a main signal at 544 nm [209,394,395,396,397]. Furthermore, Tb exhibits excellent photocatalytic [394] and gene delivery [370] properties, as well as potential bactericidal activity and an ability to inhibit cancer cell development [398]. However, Tb is harmful for the human body at high concentrations [398].…”

High-performance bioceramics are required for preventing failure and prolonging the life-time of bone grafting scaffolds and osseous implants. The proper identification and development of materials with extended functionalities addressing socio-economic needs and health problems constitute important and critical steps at the heart of clinical research. Recent findings in the realm of ion-substituted hydroxyapatite (HA) could pave the road towards significant developments in biomedicine, with an emphasis on a new generation of orthopaedic and dentistry applications, since such bioceramics are able to mimic the structural, compositional and mechanical properties of the bone mineral phase. In fact, the fascinating ability of the HA crystalline lattice to allow for the substitution of calcium ions with a plethora of cationic species has been widely explored in the recent period, with consequent modifications of its physical and chemical features, as well as its functional mechanical and in vitro and in vivo biological performance. A comprehensive inventory of the progresses achieved so far is both opportune and of paramount importance, in order to not only gather and summarize information, but to also allow fellow researchers to compare with ease and filter the best solutions for the cation substitution of HA-based materials and enable the development of multi-functional biomedical designs. The review surveys preparation and synthesis methods, pinpoints all the explored cation dopants, and discloses the full application range of substituted HA. Special attention is dedicated to the antimicrobial efficiency spectrum and cytotoxic trade-off concentration values for various cell lines, highlighting new prophylactic routes for the prevention of implant failure. Importantly, the current in vitro biological tests (widely employed to unveil the biological performance of HA-based materials), and their ability to mimic the in vivo biological interactions, are also critically assessed. Future perspectives are discussed, and a series of recommendations are underlined.

“…Por otra parte, la hidroxiapatita, obtenida por el proceso solgel presenta ventajas inherentes a este método son la alta homogeneidad y pureza de los productos obtenidos debido a que los reactivos de partida contienen impurezas mínimas, así como las menores temperaturas de síntesis comparadas con las del proceso cerámico (Jiménez-Flores, et al, 2017, González, 2012.…”

La contaminación del agua por la presencia de iones fluoruro es un problema ambiental y de salud en México y el proceso de adsorción con materiales adsorbentes de bajo costo como la zeolita natural y la hidroxiapatita han sido empleados en el proceso de adsorción debido a los pocos riesgos ambientales que implican su uso. En el presente trabajo se sintetizó hidroxiapatita y se usó zeolita natural tipo Clinoptilolita, ambos materiales fueron acondicionados con especies de óxido de hierro; todos los materiales fueron caracterizados mediante XRD, SEM e FTIR. En los estudios de adsorción se probaron los materiales en la remoción de concentraciones altas y bajas de iones flúor, obteniendo resultados muy favorables (conversiones del 90%) para la hidroxiapatita con el que se demostró la formación de fluorapatita, comprobando la adsorción química del contaminante y no así con la zeolita natural, en donde se obtuvieron menores porcentajes de remoción con una adsorción física.

In this review article the available results about application of sol-gel synthesis method for the preparation of different calcium phosphates and composite materials are summarized. The attention is paid to calcium phosphate-containing compounds which show the biological properties and could be used as potential phosphate bioceramics in medicine. It was demonstrated that the sol-gel synthesis method is a powerful tool for the synthesis of calcium hydroxyapatite and other phosphates, and different calcium phosphate-based composites at mild synthetic conditions resulted in high reproducibility, high phase purity, and desired morphology. Thus, the sol-gel synthesis method enables the researchers to develop biomaterials with superior features in terms of biomedical applications.
