a Distribution and tumor accumulation of DiR-nanoparticles in HeLa tumor-bearing mice receiving intravenous injection of the indicated formulations. b Ex vivo fluorescence imaging of the tumor and normal tissues harvested from the euthanized HeLa tumor-bearing nude mice. The images were taken 24 h after the injection. H, Li, Lu, K, S, and T represent the heart, liver, lung, kidney, spleen, and tumor, respectively. c DiR fluorescence intensity in tumor tissues collected at 24 h following systemic injection. P < 0.05. (a) 0.9% NaCl, (b) DiR-NDs, and (c) DiR-HFNDs
