(1) EGCNPs with concentrations up to 200 μg ml−1 did not have any significant effect on cell viability, when compared to control cells at the two tested time points (p value < 0.05) . However, the 24 h exposure to concentrations of 400 μg ml−1 or higher resulted in a statistically significant decrease in viability ranging from 27% (at 400 μg ml−1) to 40% (1000 μg ml−1) . (2) From 50 to 200 μg ml−1 were safe and had no harmful effect on the morphology, proliferation, and cell membrane integrity of the HLECs after 72 h exposure. |
