Green-synthesized silver nanoparticles from fresh and waste Posidonia oceanica extracts: characterization and evaluation of antibacterial, cytotoxic activity against HCT-116 cells, and ecotoxicological properties
Posidonia oceanica, an endemic Mediterranean seagrass, represents a valuable source of bioactive compounds and an abundant marine biomass waste. In this study, aqueous extracts from fresh (POV) and waste (POD) leaves of P. oceanica were employed as sustainable reducing and capping agents for the green synthesis of silv...
