Bacterial survival after exposure to pSWCNT-Ag and SWCNT-Ag. Colony forming units (CFU/ml) were evaluated from each E. coli (a), S. Typhimurium (b), and S. Anatum (c) harvested after 48 h cultures in the presence of various concentration of pSWCNT-Ag and SWCNT-Ag (0, 25, 31.25, 50, and 62.5 µg/ml). Data are mean ± SD of three independent cultures
