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.
