This study explores the eco-friendly synthesis of silver nanoparticles (AgNPs) using an aqueous extract from the leaves of an invasive species <em>Nicotiana glauca</em>. The synthesized AgNPs were thoroughly characterized using X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS), and transmission electron microscopy (TEM). DLS analysis confirmed the nanoparticles' monodispersity and stability, with an observed mean hydrodynamic diameter of 60.00 nm. XRD patterns indicated a face-centered cubic crystalline structure, with an average crystallite size of 42.58 nm. TEM imaging revealed that the nanoparticles were predominantly spherical, with sizes ranging from 50 nm to 55 nm. The AgNPs exhibited significant antifungal activity, with the largest inhibition zone measuring 26.0 mm against <em>Fusarium solani</em>, followed by 23.1 mm for <em>Aspergillus nige</em>r. This study demonstrates that silver nanoparticles synthesized from <em>Nicotiana gl</em>auca leaf extract possess potent antifungal efficacy against key pathogens and exemplify a sustainable approach by valorizing an invasive plant for eco-friendly nanotechnolog Furthermore, this study highlights the innovative use of invasive plant species like <em>N. glauca</em> as a sustainable, environmentally friendly resource for nanoparticle production. By promoting green nanotechnology, this work contributes to biodiversity conservation efforts while providing a practical approach to managing invasive alien plants.</p>
