Abstract :

— Osteoporotic bone defects pose a major clinical challenge, demanding scaffolds that combine mechanical support with bioactivity to stimulate bone regeneration. In this study, we developed a novel 3D-printed polymeric scaffold coated with APTES-functionalized mesoporous bioactive glass nanoparticles (MBGNPs) nanoparticles to address this need. The scaffold featured a four-layer architecture with 800 µm cubic pores, optimized for potential osteoblast adhesion and proliferation. MBGNPS nanoparticles and surface functionalized MBGNPSs were synthesized and thoroughly characterized by using FE-SEM, EDS, XRD, and FTIR analyses; to confirm their mesoporous structure and chemical composition. Additionally, Scaffold characterization confirmed successful nanoparticle deposition, preservation of pore architecture, and chemical integration of the coating. This study demonstrates a simple and effective strategy to fabricate mechanically robust, bioactive polymeric scaffolds, highlighting their potential as platforms for future osteoporotic bone defect engineering applications.
