Figure 1From: Cytotoxicity screening of 23 engineered nanomaterials using a test matrix of ten cell lines and three different assays BaSO 4 -induced reduction of cell viability. Metabolic activity in ten cell lines exposed to different concentrations of BaSO4 in DMEM/10% FBS or pure DMEM/10% FBS (Control). Data are expressed as% of control mean ± SD of three independent experiments with four replications each. * significantly different from control for p = 0.05.Back to article page
