Figure 2. Cell proliferation of sheep primary pleural mesothelial cells was assessed for 3 days after exposure to 0.02 mM sodium citrate (Control; n=15), or 0.2 μg/ml (n=15) (A) or 2 μg/ml (B) AgNPs of 20 nm and 60 nm (n=15). Cells were stained with crystal violet and the optical density(OD) of the extracted dye measured. Significantly different at *p<0.05 and ***p<0.001 comparison versus control, and #p<0.05 and ###p<0.001 versus 20 nm AgNPs (B).
