Grape pomace extract mediated silver nanoparticles (GPE-AgNPs) were synthesized by bio-reduction of silver ions using grape pomace extract and characterized using UV-Vis, DLS, and FTIR. The obtained particles were crystalline, round-shaped, monodisperse and stable. The achieved results indicate that silver nanoparticles varied in size with an average size of 45 nm. Synthesized GPE-AgNPs showed significant catalytic, antimicrobial and antioxidant (DPPH radical scavenging method) activities.
