Task: Answer Verification
Input (English): Question: Do gold nanoparticles induce cytotoxicity in the alveolar type-II cell lines A549 and NCIH441?
Answer: Our data suggest that the presence of contaminants, such as sodium citrate, on the surface of gold nanoparticles might play a pivotal role in inducing cytotoxicity in vitro, but does not influence the uptake of the particles in human ATII-like cell lines.
Output (English): yes
