A MIL series metal-organic framework (MOF), MIL-100(Fe), was successfully synthesized\nat the nanoscale and fully characterized by TEM, TGA, XRD, FTIR, DLS, and BET. A toxicological\nassessment was performed using two different cell lines: human normal liver cells (HL-7702) and\nhepatocellular carcinoma (HepG2). In vitro cytotoxicity of MIL-100(Fe) was evaluated by the MTT\nassay, LDH releasing rate assay, DAPI staining, and annexin V/PI double staining assay. The safe\ndose of MIL-100(Fe) was 80micro g/mL. It exhibited good biocompatibility, low cytotoxicity, and high\ncell survival rate (HL-7702 cellsâ?? viability >85.97%, HepG2 cellsâ?? viability >91.20%). Therefore,\nMIL-100(Fe) has a potential application as a drug carrier.
