Silver nanoparticles (AgNPs) are known for their unique properties and applications in fields such as medicine and environmental remediation. Recent environmental concerns and the need for sustainable technologies have spurred interest in eco-friendly synthesis methods, particularly green synthesis using plant extracts, which is a cost-effective and biocompatible alternative to traditional physical and chemical methods. Silver nanoparticles (AgNPs) were synthesized using an aqueous leaf extract of Bassia scoparia L. as a reducing and stabilizing agent, demonstrating a simple and sustainable method for nanoparticle production. Comprehensive characterization was performed using various techniques: Scanning Electron Microscopy (SEM) assessed surface morphology and size distribution, X-ray Diffraction (XRD) confirmed crystallinity, Fourier Transform Infrared Spectroscopy (FTIR) identified functional groups involved in synthesis, Ultraviolet-Visible (UV-Vis) Spectroscopy monitored surface plasmon resonance, and Zeta Potential analysis examined surface charge and colloidal stability of the AgNPs. The results confirm the successful biosynthesis of stable, crystalline silver nanoparticles, demonstrating the potential of Bassia scoparia L. as an effective plant source for green nanotechnology applications.
