The structural properties, chemical activity and biocompatibility of the surface, UV and X-ray luminescence spectra were determined. Based on them, magnetically sensitive nanocomposites (NC) and magnetic fluids containing X-ray luminescent components were created. 60S bioglass NCs with synthesized crystals in the dry state and in distilled water are characterized by luminescence upon excitation by UV and X-ray radiation. The possibility of their use as part of NCs with nanosized magnetically sensitive drug carriers and bioactive sol-gel glass (BS) is shown. Promising for the creation of fluorescent detectors of high-energy electromagnetic radiation, in the development of photo- and optoelectronic devices, etc. Samples of bioglass 60S doped with rare earth elements La and Y were synthesized, their structural properties and changes in contact with a model physiological environment (SBF Kokubo) were investigated. It was established that the interaction with the latter changes the phase composition and the ratio of amorphous and crystalline components with the formation of hydroxoapatite (HS), and the elemental composition indicates active ion exchange processes according to the theory of BS dissolution in physiological fluids. The high bioactivity of the synthesized materials was experimentally established. The GS formed on the surface of the material gives the bioglass (BS) osteoconductive properties, the ability to connect with bone tissue, as well as the corresponding ability for biodegradation. Modified BS is promising for use in trauma and orthopedic surgery for bone tissue regeneration and engineering. In order to create new types of promising implants, a technique for obtaining an adhesive tantalum oxide surface with the inclusion of Ca2+ ions in a nanostructured Ta2O layer has been developed, which is promising f Product Description popup.authors Bagatska Ganna M.
