“…In this sense, the design of a nanocomposite material formed by nanocrystalline apatite particles embedded into an MBG mesoporous wall would allow to obtain a novel third generation bioceramic with an enhanced functionality. Several routes toward the preparation of silica mesoporous–apatite composite have been explored. − The most common methods are based in grafting apatite precursors on preformed silica mesoporous material or coating apatite particles with mesoporous silica films. However, such routes do not satisfy the requirements for preserving the properties of both components, and the materials obtained in the process present very heterogeneous distribution and phase segregation. − …”

Crystalline nanoparticles are very attractive building blocks for the preparation of nanostructured materials. These particles can be dispersed in different noncrystalline mesostructured matrixes in order to obtain nanocomposite systems which combine the properties of both components broadening their functionality. In the present study, a novel nanocomposite bioceramic formed by nanocrystalline apatite particles uniformly embedded into a mesostructured SiO 2 −CaO−P 2 O 5 glass wall has been synthesized through the evaporation-induced self-assembly (EISA) method, commonly used for mesoporous bioactive glass synthesis, but accelerating the sol−gel apatite crystallization rate by strong acidification. Moreover, the use of F127 surfactant as a structure directing agent in this synthesis has allowed the homogeneous nanocrystalline apatite particles incorporation inside of the amorphous mesoporous glass. In vitro bioactive assays have shown a fast apatite-like phase formation similar to that exhibited by mesoporous bioactive glasses. Furthermore, the response of L929 fibroblasts and Saos-2 osteoblasts to this new nanocomposite has indicated a significant improvement in its biocompatibility compared with conventional mesoporous bioactive glasses.

“…Sorption experiments were conducted in many different environments and in different systems using different research techniques. [20][21][22][23][24][25] Evaluation of BPs interaction with bone usually leads to the study of sorption on HA, for example, reaction mechanisms between a BP molecule, tiludronate, and the nanocrystalline apatite surface [20] or NMR investigations of the static and dynamic structures of BPs on human bone.

Monolithic materials based on silica and hydroxyapatite was applied as tool for investigation of interactions between bone and potential antiresorptive drugs. First type of material was created on the basis of tetramethyl orthosilicate and trimethoxymethylsilane. Second type of material contained additionally chitosan in its structure. Ceramic fraction of monoliths was prepared in two ways: by incorporation of hydroxyapatite during crosslinking or by using soaking method (hydroxyapatite mineralization on the surface). Monolithic materials were prepared in two different forms: in the form of a cylinder and as a filling of a needle for monolithic in‐needle extraction (MINE) device. Several techniques were applied to evaluate the properties of 19 prepared materials: energy dispersive X‐ray spectroscopy, scanning electron microscopy, and Raman spectroscopy, which allowed to confirm and characterize occurred hydroxyapatite layer. Sorption–desorption investigation, with the sodium risedronate as test compound, was made with using ultraviolet‐visible spectroscopy, to assess the affinity of the bisphosphonate for the ceramic layer of the material as a bone substitute. One of 15 prepared MINE devices exhibits sorption ability of risedronate equal to 97%.
