Abstract– This study explores the green synthesis of copper oxide nanoparticles (CuO-NPs) using the aqueous extract of Azolla pinnata, an eco-friendly and sustainable approach to nanoparticle production. The process leverages the natural abundance and low cost of A. pinnata, aligning with green chemistry principles to minimize environmental impact. The synthesized CuO-NPs were characterized using various techniques, including X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Dynamic Light Scattering (DLS). The results revealed that the CuO-NPs possess a face-centered cubic structure with crystalline sizes ranging from 20-50 nm. The nanoparticles exhibited a predominantly spherical shape with uniform size distribution, and a capping organic layer was observed, enhancing stability. The colloidal stability of the nanoparticles, attributed to a negative zeta potential, prevents aggregation and ensures long-term stability. This research demonstrates the effectiveness of A. pinnata extract in synthesizing stable and well-characterized CuO-NPs, providing a promising alternative for sustainable nanotechnology applications in catalysis, biomedicine, and environmental remediation.
