چکیده انگلیسی
The high risk of infection caused by implantation of orthopedic bio-metals is still a daunting challenge for surgeons as it can lead to implant failure. One approach to overcome this issue is the local release of antibacterial drug through coating on the surface of a metallic implant. One ideal carrier for this purpose is hydroxyapatite (HA) particles which are bioactive, biodegradable, biocompatible and have the potential to bond to bone. In the current study, highly crystalline mesoporous HA nanostructure particles were successfully synthesized in a low-temperature solvent process with the aid of an inorganic CaCO3 template and then fully characterized. The specific surface area and the average size of the cavities of the nanostructured mesoporous HA particles were 85â¯m2/g and 20â¯nm, respectively. The feasibility of the prepared HA mesoporous nanostructures for drug delivery, using ibuprofen as a model drug, was also investigated. The as-prepared HA mesoporous nanostructures showed a high drug-loading capacity, as well as sustained drug release in a phosphate buffered saline (PBS) at a pH of 7.4. Overall, results show that HA mesoporous nanostructures gave great potential in bone regeneration and local delivery of either drugs or biomolecules.
