ABSTRACT

extract of Jasminum fluminense an eco-friendly approach. The green synthesized copper oxide nanoparticle was characterized using UV- Spectroscopy, FTIR analysis, SEM and TEM. The results of the UV- Spectroscopy study revealed that the absorption spectra of copper oxide nanoparticle formed in the reaction media has absorbance peak at 430nm. The results of FTIR spectrum of copper oxide nanoparticle revealed that copper oxide nanoparticle was surrounded by different organic molecules such as alcohols, ketones, aldehydes, carboxylic acid etc, which act as reducing and capping agents that provide stability to nanoparticle. The results of the SEM showed that the diameter of green synthesized copper oxide nanoparticle ranged from 30 nm – 60 nm in diameter and the shape was found to be in the form of spherical, cylindrical and flakes with agglomerates were also observed. The results of TEM showed the formation of well distributed spherical and cylindrical shapes with size ranges from 100 nm to 500 nm in magnification. Copper oxide nanoparticle showed antimicrobial activity against microbial pathogens used in the study except Aspergillus niger.
