英文摘要Chemotherapy resistance and bone defects caused by surgical excision of osteosarcoma have been formidable challenges for clinical treatment. Although recently developed nanocatalysts based on Fenton-like reactions for catalytic therapy demonstrate high potential to eliminate chemotherapeutic-insensitive tumors, insufficient concentration of intrinsic hydrogen peroxide (H2O2) and low intratumoral penetrability hinder their applications and therapeutic efficiency. The synchronous enriching intratumor H2O2 amount or nanoagents and promoting osteogenesis are intriguing strategies to solve the dilemma in osteosarcoma therapy. Herein, a multifunctional "all-in-one" biomaterial platform is constructed by co-loading calcium peroxide (CaO2) and iron oxide (Fe3O4) nanoparticles into a three-dimensional (3D) printing akermanite scaffold (AKT-Fe3O4-CaO2). The loaded CaO2 nanoparticles act as H2O2 sources to achieve H2O2 self-sufficient nanocatalytic osteosarcoma therapy as catalyzed by coloaded Fe3O4 nanoagents, as well as provide calcium ion (Ca2+) pools to enhance bone regeneration. The synergistic osteosarcoma-therapeutic effect is achieved from both magnetic hyperthermia as-enabled by Fe3O4 nanoparticles under alternative magnetic fields and hyperthermia-enhanced Fenton-like nanocatalytic reaction for producing highly toxic hydroxyl radicals. Importantly, the constructed 3D AKT-Fe3O4-CaO2 composite scaffolds are featured with favorable bone-regeneration activity, providing a worthy base and positive enlightenment for future osteosarcoma treatment with bone defects by the multifunctional biomaterial platforms.
