AgNP-induced cellular damage. a Phase-contrast micrographs. A549 cells were exposed to AgNPs (50–200 μg Ag/ml) for 24 h. Scale bar, 100 μm. b Cell viability. A549 cells were exposed to AgNPs (50–1000 μg Ag/ml) for 24 h. Cell viability was determined using a WST-8 assay. Each value (mean ± standard deviation, n = 3) represents the percent survival relative to untreated control cells (0 μg Ag/ml). **P < 0.01 compared to the control
