Cytotoxicity of nanoparticles to RPE-1 cells: Celltiter-glo (a) and LDH assay (b). The non-filtered, polydisperse particles displayed the most cytotoxicity while the more homogeneous and smaller particles were shown to be the least toxic. Line above samples indicates that all three values are statistically significant (p < 0.05). Asterisk denotes one sample which is statistically different from the other two (p < 0.05). Error bars represent standard deviation
