International Conference on

Swertia chirayta mediated facile green synthesis of ultra-small copper oxide nanoparticles (UCuONPs)

and their antibacterial activity

e report the antibacterial activity of ultra-small copper

oxide nanoparticles (UCuONPs). Ultra-small copper oxide

nanoparticles have been synthesized by using aqueous and

alcoholic extracts of Swertia chiryta as a reductant and stabilizer.

Thus prepared UCuONPs were in the diameter range of 2-10 nm.

The UCuONPs were characterized using Fourier transform infrared

spectroscopy, X-ray diffraction, UV-visible spectroscopy, high

resolution transmission electron microscopy, scanning electron

microscopy and energy-dispersive X-ray spectroscopy. On the

basis of these results ultra-small copper oxide nanoparticles were

successfully prepared by interaction of copper ions and plant

extracts. The as-prepared ultra-small copper oxide nanoparticles

were studied for their antibacterial activity against

Staphylococcus

aureus, Escherichia coli and Salmonella enterica

with the possible

use as antibiotic against Gram-positive and Gram-negative strains.

Results indicated that UCuONPsweremost effective against Gram-

positive bacterial strains as compared to Gram-negative ones.
