Abstract
A series of macroporous-mesoporous bioglasses (MMBGs) doped with Ag, TiO2 and Ag/TiO2 have been successfully prepared using the nature plants as the macroporous templates and P123 as the mesoporous one. The dual drug action (antifungus and anti-inflammatory) and bone regeneration systems have been obtained by Ibuprofen (Ibu) loaded. Meanwhile, the antifungus as well as drug control release profiles of these materials have been investigated. Compared with pure MMBGs, MMBGs-Ag, MMBGs-TiO2 and MMBGs-Ag/TiO2 showed much higher antimicrobial efficiency, faster hydroxyapatite-forming ability and better drug sustained release performance. The multifunctional hierarchical porous bioglasses materials may have potential applications in bone tissue engineering.
