Abstract

This study aimed to fabricate micro-nano bioactive glass (MNBG) scaffolds loaded with chemotherapeutics and siglec-15 monoclonal antibody with bone repair capability and high-active drug loading capability for postoperative treatment of osteosarcoma. Bioactive glass (BG) particles were incorporated...
