ABSTRACT |
|
|
The study highlights the fabrication of
gold nanoparticles (GNPs) by fresh leaves of Tridax procumbens
(TP), an herbal medicinal plant. The bio-reduction of auric chloride
ion (Au+3) is quite rapid, readily to be performed at room
temperature. This study describes a rapid and eco-friendly synthesis
of TP-GNPs are be done using TP leaf extract in a single pot process
and is observed when the medium turns into purple color with the
addition of aqueous Au+3. The formation of TP-GNPs is verified by
ultraviolet-visible spectroscopy. The possible functional groups of
TP leaf extract and their changes after treating with aqueous auric
chloride are evaluated by Fourier transform infrared spectroscopy.
The size of synthesized TP-GNPs is measured by dynamic light
scattering analysis, and morphology is examined by transmission
electron microscopy in nano range and energy dispersive X-ray
spectrum confirming the presence of gold. The average size of TP-GNPs
is ~7 nm and mono dispersed. Further, we apply anti-bacterial
activity on both Escherichia coli and Bacillus subtilis,
and the results suggest that the TP-GNPs suspension exhibits
anti-bacterial activity.
