a Zones of inhibition of the growth ofE. coli K12 on solid LB medium. Wells 1, 3, and 5 received gentamicin, whereas wells 2, 4, and 6 received gentamicin + gold NPs. The final antibiotic concentration in the wells was decreased by twofold dilutions and was 2.25 (wells 1 and 2), 1.13 (wells 3 and 4), and 0.563 mg mL−1(wells 5 and 6).b A diagram showing the averaged results from five independent experiments, with three replicates per experiment
