Abstract

---

The present work aims at the green synthesis of metal oxides of zinc, iron and copper using the aqueous extract of Terminalia belerica as a reductant as well as a stabilizer. The successful formation of the metal oxide nanoparticles was confirmed by UV-Vis spectroscopy. Thus prepared metal oxide nanoparticles were characterized employing Fourier transform infrared spectroscopy, X-ray diffraction spectroscopy, high-resolution transmission electron microscopy, scanning electron microscopy and energy-dispersive X-ray spectroscopy. We used these nanoparticles to demonstrate their antibacterial efficacy against some common standard bacterial pathogens including Staphylococcus aureus (ATCC-6538), Bacillus subtilis (MTCC-441), Escherichia coli (ATCC-8739) and Klebsiella pneumoniae (ATCC-43816) to find their plausible use as an alternate weapon to fight against multi-drug resistant superbugs.
