Figure 6From: Oxidative stress mediated cytotoxicity of biologically synthesized silver nanoparticles in human lung epithelial adenocarcinoma cell lineEffect of AgNPs on cell viability of A549 human lung epithelial adenocarcinoma cells. Cells were treated with silver nanoparticles (AgNPs) at several concentrations for 24 h and cytotoxicity was determined by the MTT method. The results are expressed as the mean ± SD of three separate experiments each of which contained three replicates. Treated groups showed statistically significant differences from the control group by the Student's t test (p < 0.05).Back to article page
