Abstract: Metal-organic frameworks (MOFs) are special materials formed by self-assembly of metal ions and organic ligands, with special physical and chemical properties, such as large specific surface area, excellent biocompatibility and strong pH sensitivity, etc. Through modification, they have synthesized nanomaterials with excellent performance, which have huge application prospects in treating tumors. This paper mainly reviews the properties of MOFs and their derived materials, and the application progress of MOFs in tumor drug-loaded therapy, photodynamic therapy and immunotherapy.
