FIG 1.

The antibacterial activity of AgNPs. (A and B) (A) MIC of antibiotics (left panel) and (B) AgNPs (right panel) for various sensitive (S) and resistant (R) bacteria. Abbreviations: TET, tetracycline; CIP, ciprofloxacin; MET, methicillin; VAN, vancomycin. The sensitive strains included E. coli BW25113, S. aureus ATCC 29113, and S. pneumoniae D39. (C) MIC of AgNPs for CIP-sensitive and -resistant E. coli strains after 0, 10, 11, and 12 h of light exposure. All MIC results were determined with a microdilution method in three independent biological replicates. (D) MIC of AgNPs for E. coli strains exposed to 0, 50, 100, and 500 lx of light.
