Comparably, a study by Ahmed et al. reported similar outcomes in EDX analysis, where copper nanoparticles synthesized using leaf extract of Camellia sinensis exhibited a predominant copper content (48.89%), along with elements such as oxygen (21.24%), chlorine (12.7%), and carbon (9.69%), among others. Wu et al. also observed various elemental constituents in copper nanoparticle synthesis using leaves of the same plant.
