Green Synthesis of Monometallic and Bimetallic Silver-Copper Nanoparticles Using Aqueous Extract of Ganoderma lucidum

This study explores the green synthesis of copper-silver (Cu-Ag) nanoparticles using Ganoderma lucidum extract as both a reducing and capping agent. The synthesis involved three reactions to produce silver, copper, and bimetallic Cu-Ag nanoparticles. The synthesized nanoparticles were characterized using FTIR, which confirmed the presence of functional groups such as hydroxyl, carbonyl, amine, and carboxylate, responsible for stabilizing the nanoparticles. The antibacterial activity was evaluated using the disc diffusion method, with the Cu-Ag sample showing the largest inhibition zone against Staphylococcus aureus, a Gram-positive bacteria. This work demonstrates the potential of green synthesis for producing eco-friendly nanomaterials with significant antimicrobial properties for biomedical applications.
