Figure 7
Effect of AgNPs on LDH release from A549 human lung epithelial adenocarcinoma cells. Lactate dehydrogenase (LDH) was measured by changes in optical density due to NAD+ reduction monitored at 490 nm, as described in the ‘Methods’ section. 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).
