Fig. 1 (A–C). Cytotoxicity of Nano-Co and Nano-TiO2 on PW (A), HIF-1α \(+/+) (B) and HIF-1α (−/−) (C) cells.

Fig. 1 (A–C)

Cells were treated with different doses of Nano-Co or Nano-TiO2 for 12 h and cytotoxicity was determined by SRB assay. Cells without treatment were used as the control. Data are shown as mean ± SD of three experiments with six parallel culture in each experiment. * Significant difference as compared with the control, p<0.05; # Significant difference as compared with the same dose of Nano-TiO2-treated group, p<0.05.
