Evaluation of biocompatibility. (a) Hemolysis rate of FessMOF-PEG with different concentrations. TritonX-100 (0.5%) as the positive control (P), inset is the photo of red blood cell solution after incubating with FessMOF-PEG nanoparticles. (b) Hematological indexes and biochemical data of 4T1 tumor-bearing Balb/c mice after treatments for 14 days. HGB, RBC, Lymph, WBC, CREA, UREA, AST, and ALT indicate hemoglobin, red blood cell, lymphocyte, white blood cell, creatinine, urea, aspartate transaminase, and alanine transaminase, respectively. (c) H&E staining of major organs from treated mice. Scale bars are 50 μm
