Effect of AgNPs on cell viability of L 132 and A549 cells. Cells were treated with various concentrations of AgNPs 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 Student’s t-test (p < 0.05).
