Figure 9From: Multidimensional effects of biologically synthesized silver nanoparticles in Helicobacter pylori, Helicobacter felis, and human lung (L132) and lung carcinoma A549 cells Effect of AgNPs on the generation of ROS. All test strains were treated with 1 μg/mL AgNPs for 12 h. ROS generation was measured by the XTT assay. The results are expressed as the means ± SD of three separate experiments, each of which contained three replicates. Treated groups showed statistically significant differences from the control group by Student’s t-test (p < 0.05).Back to article page
