Green Synthesis of Co3O4 Nanoparticles using Mappia Foetida Leaf Extract and its Antimicrobial Potential

Abstract

In this paper the novel green synthesis of cobalt oxide nanoparticles (Co3O4NPs) from cobalt chloride (CoCl2) using Mappia foetida leaf extract was investigated. The characterization of the Co3O4NPs was done by using UV – Vis spectroscopy, EDX, XRD and SEM analysis techniques. Comparative antibacterial study was done against gram positive and gram negative bacteria by well diffusion method in which results revealed that the biologically synthesized Co3O4NPs showed relatively similar antibacterial potential as chemically synthesized Co3O4NPs and higher antibacterial potential than that of positive control.
