The tri-metallic oxide Ni/Cr/Cu nanoparticles (NPs) were synthesized using Coriander sativum extract as the reducing agent. The precursors namely CuSO4.5H2O, Ni(NO3)2·6H2O and Cr (NO3)3·9H2O were used for the green synthesis. Further, the prepared NPs were characterized using Ultraviolet-Visible (UV-Vis) spectroscopy and X-ray diffraction (XRD) studies. Its antimicrobial property against two fungal and two bacterial species was determined by measuring the respective zone of inhibition (ZOI) in well diffusion method. A dose dependent inhibition was observed in all the four species of pathogens including Escherichia coli, Staphylococcus aureus, Aspergillus flavus and Penicillium sp. This antimicrobial property of tri-metallic oxide NPs may be utilized in the field of medical research, pharmaceutical industries and environmental sciences.
