Figure 4From: Cytotoxicity screening of 23 engineered nanomaterials using a test matrix of ten cell lines and three different assays Ti-Zr 3-induced ROS formation. Mean DCF fluorescence in ten cell lines exposed to different concentrations of Ti-Zr 3 in DMEM/10% FBS or pure DMEM/10% FBS (Control). Data are expressed as% of control mean ± SD of three independent experiments with seven replications each.* significantly different from control for p = 0.05; # significantly different from right neighbor for p = 0.05.Back to article page
