Bio-inspired silver selenide nano-chalcogens using aqueous extract of Melilotus officinalis with biological activities

For the first time, an aqueous extract of Melilotus officinalis was used to synthesize bimetallic silver selenide chalcogenide nanostructures (Ag 2 Se-NCs). The formation of NCs was confirmed and characterized by UV–visible and FTIR spectroscopy, SEM and TEM imaging, XRD and EDX crystallography, zeta potential (ZP) and size distribution (DLS). The bioactivities of biosynthesized Ag 2 Se-NCs, such as antibacterial, antibiofilm, antioxidant and...
