Figure 7From: Size-dependent cytotoxicity of silver nanoparticles in human lung cells: the role of cellular uptake, agglomeration and Ag releaseQuantification of the Ag release in cell medium. The amount of released Ag in cell medium (BEGM) after 4 and 24 h at 37°C was quantified by means of AAS and expressed as percentage from the total added Ag (10 μg/mL). Results are presented as mean ± standard deviation of 2 replicates.Back to article page
