Abstract

In this study, we report the potential use of market vegetable waste for the synthesis of gold nanoparticles (AuNPs). The AuNPs were synthesised using a green method without using any harmful chemical. The AuNPs obtained from vegetable wastes were characterised by UV– vis spectroscopy, transmission electron microscopy, scanning electron microscopy energy dispersive spectroscopy, X-ray diffraction, and Fourier transform-infrared spectroscopic (FT-IR) analysis. The particles size for the green synthesised AuNPs from vegetable waste were ranged from 10 to 70 nm. The AuNPs showed significant antibacterial activity against clinical pathogens. Hence, this attempt has shown a great potential for utilizing market vegetable waste as a bio-reductant for the synthesis of AuNPs.
