This study demonstrates the green synthesis of silver nanoparticles using aqueous extracts of Senecio vernalis plant material as a reducing and stabilizing agent. The resulting nanoparticles were characterized and tested for multiple applications including antibacterial and antioxidant activities, sun protection properties, and catalytic degradation of organic dyes. The silver nanoparticles exhibited significant antimicrobial effects against tested bacterial strains, demonstrated antioxidant capacity, showed UV-blocking potential with calculated sun protection factor values, and effectively catalyzed the degradation of synthetic dyes.


The multifunctional properties of these green-synthesized nanoparticles offer potential applications in pharmaceutical formulations, cosmetic sunscreens, and environmental remediation technologies. The environmentally friendly synthesis method using plant extracts provides a sustainable alternative to conventional chemical synthesis approaches that typically involve toxic reagents.
