Figure 3

Bio-distribution of Cd (A) and Te (B) in mice exposed to CdTe/ZnS aqQDs. ICR mice were injected via tail vein with CdTe/ZnS aqQDs (0.2 μmol/kg). Serial sacrifices were carried out at 15 min, 1 h, 6 h, 24 h, 3 d, 7 d, 14 d, and 28 d after dosing. Several organs/tissues, including heart, liver, spleen, lungs, kidneys, and brain were isolated to determine concentrations of Cd and Te with ICP-MS. The mean values of the control were deducted as the baseline (Additional file 2: Table S2). All data are represented as the mean ± SD, n = 6.
