COMPARATIVE STUDIES ON BIO AND CHEMICALLY SYNTHESIZED CUO NANOPARTICLES AND THEIR ANTIBACTERIAL ACTIVITY

Abstract

Copper oxide (CuO) nanoparticles are known as multifunctional inorganic nanoparticles with a wide range of applications. This work mainly
concentrated on the comparative study of antibacterial properties of CuO nanoparticles using two different methods. The green CuO nanoparticles
were synthesized from Cajanus Cajan plant leaf extract. The CuO nanoparticles were visually confirmed by the change of color after addition of leaf
extract into the copper acetate solution. The synthesized CuO nanoparticles were also characterized by using UV-Vis analysis, Fourier Transform
Infrared analysis (FTIR), and X-ray diffraction analysis (XRD), Field Emission Scanning Electron Microscopy (FESEM) Energy Dispersive X-Ray
(EDX) analysis. From the results, it is suggested that bio-CuO nanoparticles show more enhanced biocide activity against various human pathogens
when compared to chemical CuO nanoparticles.
