Figure 3From: Genotoxic responses to titanium dioxide nanoparticles and fullerene in gpt delta transgenic MEF cells Effect of TiO 2 and C 60 on the cellular granularity. MEF cells were exposed to graded doses of either different particle sizes of TiO2 or C60 for 24 h. After treatment, cells were detected and quantified by flow cytometry. Data were pooled from 3 independent experiments. Error bars indicated S.D.Back to article page
