Abstract
Nanotechnology has created huge impact in modern day pharmaceutical application. With such
applicability, research on nanotechnology must be done with new creativity and ideas.
Development in field is possible when number of research is carried out. So, this research is
focused on green synthesis of nanoflakes both mono (CuO and ZnO) and bi (Cu-Zn alloy) metallic
nanflakes using plant extract of Magnolia champaca (leaf) as reducing and capping agents, which
inhibits aggregation and coagulation of metal nanoflakes. The formed bimetallic nanoflakes
(CuZn) were light green in colour where as CuO was black and ZnO were white in colour.
Synthesized nanoflakes were characterized using FTIR, UV, XRD, FESEM. Simultaneously,
compared their anti-bacterial and antifungal properties to expand knowledge regarding which of
them are more effective. Cu-Zn alloy nanoflakes shows high resistivity toward gram +ve bacteria
while CuO nanoflakes shows resistivity against gram –ve and fungus and among them ZnO has
lower resistivity. Phytochemical screening of Magnolia champaca leaf is done to know the
biomolecules which involved in reduction.
