Figure 7: Long-term effect of FLG and GOs on HaCaT mitochondrial activity evaluated by the WST-8 assay.
From: Differential cytotoxic effects of graphene and graphene oxide on skin keratinocytes
Cells were exposed for increasing time intervals up to 14 days to 0.1 μg/mL FLG (A), GO1 (B), GO2 (C) and GO3 (D). Data are the mean ± SE of 3 independent experiments performed in triplicate. Statistical differences: *p < 0.05; **p < 0.01 (One-way ANOVA and Bonferroni’s post test).
