AbstractTreatment of tumorous bone defects needs complete elimination of residual cancer cells and, at the same time promotion of bone regeneration. Herein, manganese (Mn)-doped mesoporous bioactive glass-loaded with chlorine e6 (Mn-MBG/Ce6) can serve as a near-infrared (NIR) light-triggered pho-totherapy reagent for bone tumor treatment and bone regeneration. The Mn-MBG was synthesized by an evaporation-induced self-assembly (EISA) process. The addition of Mn to MBG imparted the controlled photothermal performance to Mn-MBG, but maintained well-ordered mesopores. After loading Ce6 into the ordered mesopore channel of 5Mn-MBG, the 5Mn-MBG/Ce6 displayed controlled NIR light-triggered Ce6 release. Furthermore, the mild hyperthermia induced by 5Mn-MBG/Ce6 facilitated the cellular uptake of Ce6, which significantly enhanced the efficiency of photodynamic therapy, and at the same time achieved a synergistic therapeutic effect in bone tumor therapy in vitro and in vivo . Moreover, even after short term of synergistic photodynamic and photothermal therapy, such 5Mn-MBG/Ce6 exhibited good biocompatibility and could help long term of bone tissue regeneration in vivo . Therefore, 5Mn-MBG/Ce6 could be used for ablating the residual tumor cells after surgery, and accelerating bone regeneration simultaneously, indicating a smart nanoplatform by combining photothermal/photodynamic therapy, nanomedicine delivery, and bone-forming bioactivity for treatment of tumorous bone defects.
