The toxicity of polyaniline (PANI) nanomaterials with four different aspect ratios on human lung fibroblast cells was investigated by cell viability assay, cytotoxicity assay, apoptosis/necrosis measurement, and reactive oxygen species production. The PANI nanomaterial showed shape-dependent toxicity: cytotoxicity, apoptosis, and oxidative stress increase with decreasing aspect ratio of the nanomaterials in cells. In addition, the nanotoxicity of the PANI nanomataerials was concentration- and time-dependent. |
