The anti-microbial potential of Au NPs: (a) Zones of inhibition of model bacterial strains (A) B. simplex, (B) E. coli, (C) S. aureus; 1: Ampicillin; 2–7: 10–50 µL/mL Au NPs. (b) Graph showing maximum diameter for zones of inhibition of various microbial strains. The error bars show the standard deviation. (c) Graph showing MIC values of various microbial strains.
