Facile preparation of Silver nanoparticles from Vitex negundo leaf extract with multiple applications

Abstract

Synthesis of silver nano particles following green protocols is an emerging area of interest throughout the world, as it has multiple applications in different fields. Moreover the methods are non-toxic, sustainable, eco-friendly and economically viable ones. In the current work, that we have presented is an approach towards the development of zero cost and eco-friendly approach for the preparation of nanoparticles following the green route, using the leaf extract of Vitex negundo, a common medicinal plant in South India. The specific phenomenon of Surface Plasmon Resonance (SPR) has been used for the depiction of the silver nano particles prepared. The silver nanoparticles created was characterized by using UV-Visible Spectroscopy and its performance towards the naked eye detection of several heavy metal ions was done. The larvicidal activity of silver nano particles were assessed as per the standards prescribed by WHO.

“…Nanotechnology is a promising field nowadays due to its multiple applications in various industries 1 . Nanoparticles having the range of 1-100 nm have interesting properties as compare to their bulk counterpart.…”

Vitex negundo assisted green synthesis of metallic nanoparticles with different applications: a mini review

“…The percentage mortality of larvae was found concentration dependent to silver nanoparticles, increasing from 1 mg/L to 5 mg/L. They also tried their utilities in detection of heavy metals chromium, nickel, lead, mercury based on change in color in addition to solutions, K 2 Cr 2 O 7 , NiSO 4 .6H 2 O, Pb(NO 3 ) 2 , and HgCl 2 respectively [56].…”
