a) Agar diffusion Disk-diffusion assays of penicillin-G, PCo-Peni conjugates and Au@PCo-Peni NPs against (i) S.aureus, (i)E. coli, (i) K. pneumonia, and (iv) P. vulgaris. 30 μL aqueous solution of antimicrobial agents with different weights (5-15 μg) was dropwise added to disks, and the culture dishes were incubated in the oven for 18 h at 28 °C. b) OD600 values and c) inhibitory percentage of four bacteria incubated with penicillin-G, PCo-Peni and Au@PCo-Peni NPs, respectively. The tryptic soy broth (TSB) solutions of four different bacteria without any antimicrobial agents were used as the control groups. The 96-well plates were cultured shakily for 12 hours at 37 °C.
