  • Abstract

    The use of plant material for synthesis of nanoparticles is a green technology. This green technique was used for synthesis of copper nanoparticles by biologically reducing copper sulphate solution with aqueous Syzygium Cumin leaf extract at pH 5.0. The formation of copper nanoparticles was indicated by the colour change from yellow to brown. The UV-Visible spectrum of copper nanoparticles gave surface Plasmon resonance (SPR) of 190 nm. The synthesized nanoparticles were characterized using scanning electron microscopy (SEM), x-ray, diffraction (XRD) and FTIR, These biologically synthesized copper nanoparticles were tested for antimicrobial activity against human pathogens viz. Bacillus subtilis and E-coli. Presence of elemental copper was revealed by EDAX. These biologically synthesized copper nanoparticles were found to be effective in controlling growth of human pathogens viz., Bacillus subtilis and E-coli.
