In vitro cytotoxicity assay for SWCNTs-Ag and pSWCNTs-Ag. (a) Viability of A549 cells exposed to SWCNTs-Ag. (b) Cell viability of A549 cells exposed to various concentrations of pSWCNTs-Ag. (c) J774 cell viability exposed to SWCNTs-Ag. (d) Cell viability of J774 treated with pSWCNTs-Ag. (e) Hep-2 cells viability treated with SWCNTsAg. (f) Viability of Hep-2 cells exposed to pSWCNTs-Ag. All the cells were treated with nanocomposites for 24 and 48 h and statistical differences were calculated compared to controls. All values were expressed as fold change expressed compared to non-treated bacteria. ^*when p ≤ 0.05 indicate significant differences; ^**when p ≤ 0.01 indicate highly significant differences. Error bars represent standard deviations of the results determined with at least 3 biological replicates.
