From: Gold nanoparticles induce cytotoxicity in the alveolar type-II cell lines A549 and NCIH441
Comparison of the proliferation of the cell lines A549 and NCIH441 exposed to gold nanoparticles. The cell lines A549 (A) and NCIH441 (B) in the logarithmic growth phase were exposed to AuNPs for 24, 48 and 72 hr. Each result represents the mean proliferation ± standard deviation (SD) of three independent experiments and each of these was performed in triplicate. Cell proliferation was calculated as the percentage of the viable cells compared to the untreated controls.
