Figure 8

Intracellular concentration of ATP after exposure to PVC (■) and PMMA (Inline graphic ) NPs at different concentrations for (a) 24 h, (b) 48 h, (c) 96 h and (d) 120 h. The data for 72 h incubation is given in the supporting information, Figure S8. The results are given as % ATP level with respect to control (untreated cells) and are represented as the mean ± SEM of three experiments. Statistical analysis was done by one-way ANOVA (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001) compared to control (untreated cells).
