Extracellular one-pot synthesis of nanosilver using Hyssopus officinalis L.: A biophysical approach on bioconstituent-Ag+ interactions

Abstract

In this study, synthesis of silver nanoparticles (AgNPs) has been reported using extract of Hyssopus officinalis L. by the conventional heating and microwave irradiation. The as-prepared AgNPs by both approaches were characterized using UV-vis, Fourier transform infrared spectroscopy, X-ray diffraction, SEM-EDS, transmission electron microscopy, and dynamic light scattering. The obtained data revealed that as-synthesized AgNPs by microwave irradiation (900 W) and conventional heating (100 degrees C) have average size lesser than 50 nm. Moreover, a biophysical approach on bioconstituent-Ag+ interactions has been performed. The creation of AgNPs using bioconstituents in minimal time opens the way for future studies on AgNPs toxicity without risking interference from potentially toxic reagents.
