Green synthesis of CuO nanoparticles using Mimosa pudica leaf extract for antibacterial activity

Abstract

Herein, we report the preparation of copper oxide nanoparticles (NPs) by low temperature combustion synthesis using Mimosa pudica leaf extract as fuel material. The synthesized particles are well crystalline in nature and average crystallite size was found to be 27–40 nm. The morphology of the copper oxide nanoparticles is weakly bounded agglomerated. Further, as-formed CuO NPs exhibit significant antibacterial activity against pathogenic bacterial strains namely Gram –ve Escherichia coli, Gram + ve bacteria Staphylococcus aureus.
