Silver Nanoparticles: Plant‐Mediated Approach for Synthesis, Characterization, and Dual Applications

ABSTRACT The present work describes a green approach to the synthesis of silver nanoparticles (AgNPs) using Syzygium cumini leaves. This plant leaves extract offers strong capping and reducing abilities in the synthesis process. After synthesis, these nanoparticles were characterized by using different experimental tools to determine the particle size, chemical stability, morphology, crystallinity, optical response, and functional groups. AgNPs exhibited an absorbance peak at 440 nm via UV–visible spectroscopy. The DLS study reported an average particle size about 20 nm and a zeta potential of ‐29 mV. XRD confirmed that these particles have a face‐centered cubic structure. AgNP expressed good antibacterial activity against Escherichia coli and Staphylococcus aureus . Furthermore, AgNPs revealed higher photocatalytic degradation (90%) of the methylene blue (MB) dye under sunlight.
