Zinc oxide nanoparticles (ZnO NPs) have attracted significant interest in recent years due to their wide range of applications, particularly in food fortification, biomedical, and environmental fields. In the present study, ZnO nanoparticles were synthesized using an eco-friendly green synthesis method employing Adhatoda vasica leaf extract. This method is simple, non-toxic, and environmentally sustainable. The synthesized nanoparticles were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Ultraviolet–Visible (UV–Vis) spectroscopy, and Scanning Electron Microscopy (SEM). XRD analysis was used to determine the crystalline structure and particle size, FTIR analysis to identify functional groups, UV–Vis spectroscopy to calculate the optical band gap, and SEM to study surface morphology. The results confirmed the successful formation of hexagonal ZnO nanoparticles with an average particle size of 30.94 nm. These biosynthesized ZnO nanoparticles show strong potential for applications such as antimicrobial agents, biosensors, and water treatment.
