Integrative treatment of anti-tumor/bone repair by combination of MoS2 nanosheets with 3D printed bioactive borosilicate glass scaffolds

Chemical Engineering Journal 2020 Volume 396, Article 125081

Malignant bone tumors have caused great obstacles and serious illnesses for tumor recurrence and difficulty in reconstructing and repairing large defects after tumorectomy. Additionally, long-term efficacy, satisfactory biocompatibility and excellent properties for anti-tumor agents are necessary in the biomedical field. To solve these problems, a novel idea has been proposed on building an integrative anti-tumor/bone repairing scaffold by covering photothermal therapy (PTT) composite MoS2-PLGA film on the surface of borosilicate bioactive glass (BG). In our study, the MoS2-integrated composite BG (BGM) scaffolds can rapidly and effectively elevate temperature, and they exhibited excellent photothermal stability, under 808 nm laser irradiation. Notably,…

Silicone resin derived larnite/C scaffolds via 3D printing for potential tumor therapy and bone regeneration

Chemical Engineering Journal 2020 Volume 382, Article 122928

Three dimensional (3D) printing has been used to fabricate bioceramic scaffolds for treating the tumor-related defects in recent years, but the fabrication process and the introduction of anti-tumor agents are still challenging. In this study, porous free carbon-embedding larnite (larnite/C) scaffolds have been successfully fabricated by 3D printing of the silicone resin loaded with CaCO3 filler and high temperature treatment under an inert atmosphere. The fabricated larnite/C scaffolds had uniform interconnected macropores (ca. 400 μm), and exhibited excellent photothermal effect, which was able to kill human osteosarcoma cells (MNNG/HOS) and inhibit the tumor growth in nude mice. Moreover, the larnite/C scaffolds…
