Ion-Containing Mesoporous Silica-Based Nanomaterials for Bone Regeneration: Emphasis on In Situ Co-Condensation, Multifunctional Bioactivity, and Spatiotemporal Delivery
Bone defects remain difficult to treat because conventional grafting approaches may cause infection, inflammation, donor-site morbidity, or graft rejection. Mesoporous silica nanoparticles (MSNs) have emerged as versatile nanomaterials for drug delivery owing to their large surface area, tunable pore structure, high lo...
