pH-Responsive Nanoparticle-Coated Calcium Phosphate Granules for Bone Cancer Therapy. (PubMed, Small)
In this study, we develop β-tricalcium phosphate (β-TCP) granules decorated with selenium (Se)-doped mesoporous silica nanoparticles (SeMIA@TCP), in which nanoparticles are functionalized with imine bonds for acidic pH-responsive detachment and alendronate for strong β-TCP binding...Furthermore, the released nanoparticles enhanced alkaline phosphatase (ALP) expression and mineralization in hMSCs, underscoring their osteogenic potential. Collectively, these results demonstrate the potential of tumor microenvironment-responsive Se-doped MSN-assembled TCP granules as a design platform for bifunctional scaffolds in bone cancer treatment.
