Abstract

In this study, Acalypha indica was utilized to green synthesize gold nanoparticles. The characteristics of the synthesized nanoparticles were observed through UV-Vis, FTIR, TEM, particle size analyzer, and XRD. Furthermore, the nanoparticles were investigated for antibacterial properties. The particle size of gold nanoparticle was around 50 – 100 nm, and the antibacterial property of the nanoparticle was assessed using agar well diffusion, swarming motility, MIC, and protein leakage assay. The gold nanoparticles were observed to be active against E .coli alone with MIC at 160 µg, and it was observed to inhibit its swarming motility and to make the cell leak out proteins.
