Green synthesis and characterization of silver nanoparticles using leaf extract of Tridax procumbens

Abstract

An ecofriendly approach for green synthesis of nanoparticles using natural plant extracts is gaining a notable importance now a days. In the present study, Tridax procumbens leaf has been used to produce the silver nanoparticles (AgNps) from two solvent systems (distilled water and 50% alcohol). Biosynthesis of AgNps from the leaf extracts was carried out and the characterization of the synthesized AgNps was done using UV-Visible spectroscopy, Particle Size Analysis and Scanning Electron Microscope (SEM). Both the extracts exhibited significant results for the biosynthesis of AgNps by using silver nitrate as a reducing agent, the synthesis of AgNps was assertained by colour change from yellowish green to dark brown. The UV-Visible spectroscopy revealed the absorption maxima at 230nm and 235nm for distilled water and 50% alcohol AgNps respectively. The nanoparticle sizes were in the range from 20-154nm which was ascertained from Particle Size Analysis and Scanning Electron Microscope (SEM). The use of nanotechnology in the textile industry has increased rapidly due to its unique and valuable properties. Also, there is an considerable potential for profitable applications of nanotechnology in cotton and other textile industries.
