Optical and morphological properties of Ag nanoparticles synthesized by Artemisia lerchiana W. extract

The development of green synthesis of nanoparticles has attracted attention due to its easy preparation, less chemical processing and eco-friendly nature. Synthesis of metal nanoparticles using plant extracts is one of the simplest, convenient, economical and eco-friendly methods that reduce the impact of toxic chemicals. Thus, in recent years, eco-friendly processes for the rapid synthesis of silver nanoparticles using aqueous extracts of plant parts such as leaves, bark, roots, etc. have been reported. Artemisia lerchiana is a widely used medicinal plant due to its bioactive compounds. This article targets a bio-oriented audience and summarizes the methods used in their characterization. In the study, silver nanoparticles (AgNPs) were successfully synthesized via green synthesis using AgNO3 (silver solution), and Artemisia lerchiana plant. The structures of the synthesized silver nanoparticles were elucidated by UV-Vis, TEM and Zeta potential spectroscopic analyses. The UV-vis spectra showed an absorption at 480 nm. TEM analysis showed that the particles were spherical in nature with a size distribution ranging from 4-19 nm. Zeta size and zeta potential analyses revealed that the average size distribution of AgNPs was 165 nm and the surface charge was -20 mV.
