NR assay activity in dTHP-1 M0 macrophages exposed to various concentrations of carbon-based NMs for 24 h. Data is presented as a percentage of measured NR absorbance at 540 nm relative to the untreated control (set as 100%). Each bar represents the mean ± SD of three independent experiments (n = 3). “*” indicates a statistically significant difference from the control group by the one-way ANOVA, followed by Dunnett’s multiple comparisons test with p < 0.05.
