Summary

This study presents an eco-friendly, bio-engineered approach for synthesizing zinc oxide nanoparticles (ZnO NPs) using <i>Elettaria cardamomum</i> pod (<i>EC</i>-pod) extract, offering a sustainable alternative for environmental remediation and antimicrobial applications. X-ray diffraction (XRD) analysis confirms the wurtzite crystalline phase, with an average particle size of 20.87 nm. Ultraviolet-visible (UV-Vis) spectroscopy reveals a characteristic absorption peak at 372 nm, corresponding to an energy band gap of 3.33 eV. Fourier-transform infrared (FTIR) spectroscopy highlights the role of phytochemicals as capping and stabilizing agents. Field emission scanning electron microscopy (FESEM) and high-resolution transmission electron microscopy (HRTEM) confirm multi-architectural morphol
