Cytotoxicity of Nano-Ni and Nano-TiO2 in HaCaT cells. HaCaT cells were seeded into 96-well plates and treated with different concentrations of Nano-Ni or Nano-TiO2 for 24 h. Cells without treatment were used as control. The cytotoxicity was determined by MTS assay (a) and SRB assay (b). Data represent mean ± SE (n = 6). * Significant difference as compared with the control group, p < 0.05; # Significant difference as compared with the same dose of Nano-TiO2-treated group, p < 0.05
