(a) Linear regression curve showing the decrease of the viability of keratinocytes depending on the NPs concentration. A431 cell line is showing an increased resistance to the toxicity of GNPs compared to HaCaT cells. The differences in the cytotoxicity of GNPs towards the two cell lines were significant only at concentrations above 15 μg/mL (two-way ANOVA) ; (b) comparison of the cytotoxic effect of GNPs-CM with citrate coated GNPs (GNPs-C) on HaCaT cells, by two-way ANOVA and Bonferroni posttest .
