Effects of the organic nanoparticles on cell viability measured in the WST-8 assay performed by the three individual partner laboratories BMTZ, RIVM, and SINTEF. In the bar charts, mean cell viability (%) in comparison to the cell culture medium control for each combination of cell line and organic nanoparticles tested is shown. Standard deviation of mean is indicated by whiskers. Cells were incubated for 24 h with the organic nanoparticles and controls. Subsequently, a WST-8 assay was performed as described in the method section. Data was acquired from three independent experiments (n = 3) with up to 8 technical repeats each (N = 8). An ANOVA was performed for the statistical analysis of the WST-8 assay results in comparison to the cell culture medium control, and significance levels were given as p < 0.005 (***), p < 0.01 (**), and p < 0.05 (*)
