Figure 7. Intracellular Cu2+ uptake.

Figure 7

Cells were incubated with 4 nm and 24 nm CuO NPs, Cu(NO3)2 and NaNO3 at a dose of 0.12 µM Cu2+ concentration(10 µg/ml CuO NPs) for 1 h (A), 4 h (B), 24 h (C) and 48 h (D). Data are expressed as mean ± SD (n = 3). One-way analysis of variance with Bonferroni’s multiple comparisons post-test (the comparison between all groups to the control and between 4nm and 24 nm CuO NPs) was performed. *** p < 0.001, * p < 0.05.
