Abstract

Currently, there is an increasing commercial demand for nanoparticles due to their wide applicability in
variousmarkets, such asmedicine, catalysis, electronics, chemistry and energy.In this report, a simple and
eco-friendly chemical reaction for the synthesis of silver nanoparticles (AgNPs) from Artemisia nilagirica
(Asteraceae) has been developed. Silver nitrate was used as the metal precursor and hydrazine hydrate as
a reducing agent. Scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDX) were
used to characterise the nanoparticles obtained from A. nilagirica. The morphology of the AgNPs was
determined by SEM and the average diameter of the particles was determined as 70–90 nm. The EDX
analysis of the nanoparticles dispersion, using a range of 2–4 keV, confirmed the presence of elemental
silver, with no other impurity peaks detected. In addition, the characterised AgNPs has the potential for
various medical and industrial applications. The results showed that microbial susceptibility to AgNPs is
different for each microorganism.
