Abstract
A
simple, rapid, onsite and green biological strategy for the fabrication of
silver nanoparticles (AgNPs) using Curcuma longa aqueous root extract has been
reported in the current study. Curcuma longa aqueous root extract was used as
reducing agent and protecting source which led to the formation of silver
nanoparticles. Various reaction parameters were optimized in order to achieve
monodispersed spherical silver nanoparticles having a large surface to volume
ratio. Optimization of the concentration of precursor salt, the volume of
Curcuma longa aqueous extract, temperature and pH effect was carried out to
obtain small dimensional stable biosynthesized silver nanoparticles. As prepared Curcuma-AgNPs were chacterized by various
techniques such as Fourier transform infrared (FTIR) Spectroscopy Ultra
Violet-Visible (UV-Vis) spectroscopy, Transmission Electron Microscopy (TEM),
X-ray Diffractometry (XRD) and Atomic Force Microscopy (AFM). These techniques showed that fabricated
Curcuma-AgNPs were highly dispersed, spherical and crystalline in nature.
TEM analysis indicated that most of the nanoparticles were spherical having an
average size of 30.3±2nm.
