Supplementary data: 0 h 2.0 h Time 0.5 h 1.0 h Dilution ① ② ③ ④ ⑤ ~ ⑧ ① ② ③ ④ ⑤ ~ ⑧ ① ② ③ ④ ⑤ ~ ⑧ ① ② ③ ④ ⑤ ~ ⑧ Control CDT-Ag1 CDT-Ag2 CDT-Ag3 Free-CDT Fig. 2S Antimicrobial activity of Ag nanoparticles coated with different concentrations of CDT against Escherichia coli.After mixing E. coli and Ag nanoparticles, indicated by CDT-Ag1-3, 20 µl of reactions were sampled at 0-2 hours shown at the top of each photo.Control means no addition of Ag materials, and free CDT means addition of CDT regent without Ag. Samples and seven ten-fold serial dilutions are illustrated by numbers ①~⑧, for instance, each sample shown by ① should contain 1.4 x 103E. coli cells if no antimicrobial activities were presented.
