Oxidative damage and morphological changes in E. coli stimulated by Cit@AgNPs.

Notes: (A) MDA production. Scanning electron microscopic images of E. coli samples from the control (B), Cit@AgNPs (C), Ag⁺ (D), Cit@AgNPs plus 1 mM GSH (E), and Cit@AgNPs plus 0.1 mM Na₂S₂O₃ (F). (G) 8-oxo-dG generation in E. coli with different treatments as indicated. The concentrations of Cit@AgNPs and AgNO₃ were 15 and 0.5 μg/mL, respectively. The exposure lasted for 6 h.

Abbreviations: 8-oxo-dG, 8-oxoguanine; AgNPs, silver nanoparticles; E. coli, Escherichia coli; GSH, glutathione; MDA, malonyldialdehyde; Cit, citrate; MPA, mercaptopropionic acid; MHA, mercaptohexanoic acid; MPS, mercaptopropionic sulfonic acid.
