Proliferation/viability of A549 cells exposed to different NMs and analyzed by ECSIS. Cells were exposed for 24 h to TiO2 (A and B), CeO2 (C and D) or Ag (E and F) NMs at different concentrations. The data is presented as real-time cell proliferation (A, C and E) and fold-change vs control at the end of exposure (B, D and F). Arrows in A, C, and E indicate the beginning of exposure. Statistically significant difference respect to negative control according to one-way ANOVA with Dunnett’s post-hoc test, *p < 0.05, **p < 0.01, ***p < 0.001
