TEM images of E. coli with NPs at different time points. (A−E) E. coli with citrate Au NPs at (A) 3 h, (B) and (D) 6 h, (C) and (E) 9 h.(Inset) Magnified 100 nm complex pointed by arrows. (F−I) E. coli with PAH Au NPs at (F) 3 h, (G) 6 h, (H) and (I) 9 h.(J−N) E. coli with Ag NPs at (J) 3 h, (K) and (M) 6 h, (L) and (N) 9 h. Arrows point to NPs (A−G, J−N) and hollow cells (H and I).
