Abstract
New trend of an eco-friendly process for the synthesis of silver nanoparticles (AgNPs)
is an important aspect in the field of nanotechnology. In recent years, the utilization
of secondary metabolites from plant leaf broth has emerged as a novel technology
for the synthesis of various nanoparticles. In this report, silver nanoparticles
were synthesized by the leaf extract of Randia dumetorum. Effect of different reaction
parameters such as precursor salt concentration and leaf broth percentage morphology
of the (AgNPs) were analyzed. The plant biomolecules induce the reduction of Ag1+
ions to Ag0 nanoparticles and also act as a capping and stabilizing agent. The formation
of (AgNPs) was monitored by absorbance spectra of UV-visible spectrophotometer at
different stages during the synthesis process.
The biosynthesized (AgNPs) were characterized by different instrumental techniques
and the particles obtained are crystalline having spherical shape with the average
size 25 nm and are highly stable. The optimum conditions for synthesis are as follows:
percentage of seed broth 5%, [AgNO3] = 1 milimole and temperature 85 °C. The present
study could prove to have an enormous impact in the immediate future to synthesize
metallic nanoparticles on an industrial scale, biological activities, etc.
