Bone defects caused by trauma, tumors, and osteoarthritis have a significant impact on the quality of life and health of patients. Biomaterials are widely used for repairing bone defects and treating orthopedic diseases, but their effectiveness is still unsatisfactory in cases involving tumor, inflammation, and bacterial infection. Metal-organic frameworks (MOFs) materials, with their high specific surface, high porosity, controlled degradability, and variable composition, have shown great potential for functionalizing biomaterials and have achieved significant improvements. This review summarizes recent progress in utilizing MOFs functionalized biomaterials for enhancing bone repair and therapeutic effects, including enhanced bone regeneration, antibacterial, anti-inflammatory, and anti-tumor functions.
Bone defects induced by bone trauma, tumors and osteoarthritis greatly affect the life quality and health of patients. The biomaterials with numerous advantages are becoming the most preferred options for repairing bone defects and treating orthopedic diseases. However, their repairing effects remains unsatisfactory, especially in bone defects suffering from tumor, inflammation, and/or bacterial infection. There are several strategies to functionalize biomaterials, but a more general and efficient method is essential for accomplishing the functionalization of biomaterials. Possessing high specific surface, high porosity, controlled degradability and variable composition, metal-organic frameworks (MOFs) materials are inherently advantageous for functionalizing biomaterials, with tremendous improvements having been achieved. This review summarizes recent progresses in MOFs functionalized biomaterials for promoting bone repair and therapeutic effects. In specific, by utilizing various properties of diverse MOFs materials, integrated MOFs functionalized biomaterials achieve enhanced bone regeneration, antibacterial, anti-inflammatory and anti-tumor functions. Finally, the summary and prospects of on the development of MOFs-functionalized biomaterials for promoting bone repair were discussed.
