From: Gold nanoparticles induce cytotoxicity in the alveolar type-II cell lines A549 and NCIH441
Comparison of the cytotoxicity induced by gold nanoparticles in the cell lines A549 and NCIH441: lactate dehydrogenase release. The cell lines A549 (A) and NCIH441 (B) in the logarithmic growth phase were exposed to AuNPs for 24, 48 and 72 hr. The gold-induced cytotoxicity was measured by LDH release assay. Each result represents the mean LDH release ± standard deviation (SD) of three independent experiments and each of these was performed in triplicate.
