Obtaining Silver, Copper, and Cobalt Nanoparticles Using Aqueous Extracts from Eucalyptus globulus Leaves

This research and technological development project focuses on the sustainable synthesis of metallic nanoparticles (AgNPs, CuNPs, and CoNPs) by leveraging the phytochemical richness of the Eucalyptus globulus plant species. The problem addressed is the reliance on conventional nanoparticle synthesis methods that are either costly or environmentally polluting. The proposed solution is to implement a green chemistry approach, using aqueous extracts derived from both fresh leaves and the hydrodistillation residue of eucalyptus, which contain biomolecules with reducing and stabilizing potential. Key stages include optimizing the extraction of phenolic compounds, phytochemical characterization, antioxidant evaluation (DPPH and ABTS), optimized synthesis of the NPs, and their subsequent morphological and size characterization using UV-Visible spectrophotometry and Transmission Electron Microscopy (TEM). The ultimate goal is to generate high-value-added products from a common plant resource and its byproducts, promoting environmental and economic sustainability, and aiming for publication in indexed journals (Scopus/WoS).<br/><br/><b>Goal</b>: <br/>To synthesize silver (AgNPs), copper (CuNPs), and cobalt (CoNPs) nanoparticles through green chemistry processes, utilizing aqueous extracts obtained from fresh leaves and the hydrodistillation byproduct of Eucalyptus globulus.<br/><br/><b>Research lines</b>: <br/>biological activity
