Evaluation of morphological changes in bacteria upon their interaction with SWCNTs-Ag and pSWCNTs-Ag by SEM (a-c) and TEM (d-j). (a) Non treated Salmonella Typhimurium. (b) Salmonella Typhimurium treated with SWCNTs-Ag. (c) Treatment with pSWCNTs-Ag. (d) Non-treated bacteria. (e-g) Bacteria exposed to SWCNTs-Ag; (g) is magnified inset of (f). (h-j) Bacteria exposed to pSWCNTs-Ag; (j) is magnified inset of (i). Black solid arrows indicate lysis of the cells. White solid block arrows indicate dissolved entities. White line arrows indicate pore formation. Black arrow-heads represent nanocomposites, whereas white arrow-heads indicate cell debris. Dotted line black arrows show empty ghost cells. Two headed arrow indicates the presence of nanocomposites.
