Abstract

The present work presents the results of a straightforward, no-toxic and eco-friendly process for the green synthesis of gold and silver nanoparticles using the leaf extract from Eucalyptus macrocarpa. The process was conducted at room temperature (24 °C) with the leaf extract acting as both reducing agent and stabilising agent. Particle formation was monitored during synthesis using UV-visible spectroscopy. X-ray diffraction analysis and Energy Dispersive Spectroscopy (EDS) confirmed the presence of metal nanoparticles. While transmission electron microscopy (TEM) and field emission scanning electron microscopy (FESEM) were used to determine and confirm particle size and morphology.
