Live/ dead staining of bacteria exposed to different nanocomposites. 1 × 105 cfu/mL bacteria were exposed to 12.5 μg/mL of nanocomposites for 16 h and bacteria were stained using Baclight bacterial viability kits. (a) Non-treated bacteria. (b) Bacteria exposed to SWCNTs-Ag (c) pSWCNTs-Ag treated bacteria. (d) Ratio of green/red colored bacteria upon exposure to nanocomposites. All values were considered to be significant * at p ≤ 0.05 * or ** highly significant at p ≤ 0.01. Error bars represent standard deviations of the results determined with at least six replicates. The images are at 10× magnification. Scale bars: ~15 μm
