Abstract

Vegetable mediated synthesis of nanoparticles is a green chemistry approach that connects nanotechnology and biotechnology. In the present investigation, we have used a fast, convenient and environment friendly method for the synthesis of copper nanoparticles by biologically reducing copper nanoparticles with aqueous extract of Annona Muricata under optimum conditions (pH 7.2). The formation of copper nanoparticles was indicated by the colour change from blue to pale brown. Biosynthesized nanoparticles were characterized by UV-Vis, XRD, SEM, Particle size analysis, Zeta potential analysis and FT-IR analysis. These biologically synthesized copper nanoparticles were tested for antimicrobial activity against three human pathogens viz, E.Coli, Klbesiella pneumoniae and Staphylococcus aureus.

Keywords: Annona Muricata, UV-Vis, XRD, SEM, FT-IR and Antimicrobial activity.
