Nanostructured material comprising a biocompatible calcium phosphate glass, sol-gel process for its preparation and medical use thereof

摘要

The present invention relates to a nanostructured material comprising a biocompatible calcium phosphate glass in the system P2O5-CaO-MgO-Y2O-TiO2, wherein Y is K or Na. The preferred composition in mol% is 44.5 P2O5, 44.5 CaO, y Y2O, 11-y TiO2 with y ranging from more than 0 up to 11 The present invention also relates to a process for the preparation of said nanostructured material using the sol-gel method, and its uses as a tuneable control ion release agent with specific target cell signalling, particularly for bone tissue regeneration.
