Abstract
In an attempt to design rapid, efficient and eco-friendly process to
fabricate nanoparticles with potent biomedical applications, herein we
report for the first time synthesis of copper nanoparticle (CuNPs) using
three medicinal plants, B. prionitis leaf extract (BPLE), L. chinensis
peel extract (LCPE) and P. orientalis leaf extract (POLE). The
synthesis was completed within 5 h indicated by visible colour change
and UV-visible spectroscopy. High resolution transmission electron
microscopy revealed that the bioreduced CuNPs were very small.
CuNPs synthesized by BPLE were between 11 to 15 nm while for
POLE they were between 90 to 200 nm. LCPE synthesized CuNPs in a
size range between 10 to 100 nm. Further the CuNPs were characterized using energy
dispersive spectroscopy (EDS), dynamic light scattering (DLS) and fourier transform infrared
spectroscopy (FTIR). Both α-amylase and α-glucosidase were found to be inhibited by the
CuNPs providing the strong rationale for their further use in clinical studies as candidate nanomedicine against Type II Diabetes Mellitus.
Keywords: Barleria prionitis, Litchi chinensis, Platanus orientalis, copper nanoparticle, ?-amylase, ?-glucosidase.
