Cytotoxicity and Genotoxicity of Panel of Single- and Multiwalled Carbon Nanotubes: In Vitro Effects on Normal Syrian Hamster Embryo and Immortalized V79 Hamster Lung Cells

Figure 2

Effect of carbon nanotubes on cell viability assessed by the WST assay. Results are expressed as the percentage of delta OD (OD 450 nm–OD 690 nm) in treated cells ± SD compared to control cells (100 %) after 24 h of treatment with CNT samples. Single- or double-walled carbon nanotubes in (a) V79 cells and (b) SHE cells. Multiwalled carbon nanotubes in (c) V79 cells and (d) SHE cells. Sample concentrations are expressed as μg per cm² of cell culture surface. At least three independent experiments were realized for every point. Statistically significant () decrease in cell viability compared to control.
