title = "Cytotoxicity of nano-materials on human bronchial epithelial cell",
abstract = "This study was undertaken to address the current deficient knowledge of cellular response to nano sized particle exposure. [4] The aim of this study was to investigate the in vitro responses of human bronchial epithelial cells (BEAS-2B) after exposure to nano-materials (Ag and CNT). BEAS-2B cell viability decreased with decreasing doses of Ag (diameters : 40-70 and 100 nm) and MWCNT (diameters : 4-6 and 10-15 nm) nano-materials. At the higher exposure (≥200 ug/ml), all materials induced significant cell damage. Nano Ag materials increased apoptosis and cytokine expression (IL-6 and IL-8) when over 100 ug/ml concentration. All MWCNTs weakly increased apoptosis and did not significantly increased cytokine expression. In conclusion, we suggest that Ag and MWCNT nanomaterials induce variable extents of cellular toxicity in a dose-dependent and size-dependent.",
