Fig. 4. Biocompatibility study of the HLZ-BTED dots. (A) Cell viability of 4T1 and L929 cells after incubation with different concentrations of the HLZ-BTED dots for 24 h (n = 3). (B) Body weight of normal mice on different days (n = 3) treated with PBS, 7.5 mg kg–1, and 15 mg kg–1HLZ-BTED dots. (C) Representative hematoxylin and eosin stained images of major organs (heart, liver, spleen, lungs, and kidneys) from the control mice and HLZ-BTED dot injected mice at 31 days post-treatment. Scale bar: 100 μm.
