Tailored Synthesis of Silver Nanoparticles using Polyphenolic and Flavonoid-rich Leaf Extract of Dryopteris cristata L. and Insights into its Antioxidant Potency
Year: 2025
Type: article
Abstract: Biosynthesized nanoparticles are increasingly recognized for their potential due to the biologically active secondary metabolites in plants that facilitate green synthesis and offer unique biological applications. This study presents a simple, eco-friendly and cost-effective method for the synthesis of silver nanoparticles using the aqueous leaf extract of Dryopteris cristata L., which serves as both a reducing and capping agent. Characterization through UV-visible spectroscopy (UV-Vis.), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray analysis (SEM-EDX), and transmission electron microscopy (TEM) analyses confirmed the properties of the Dryopteris cristata-silver nanoparticles (Dc-AgNPs). Phytochemical analysis identified the compounds responsible for nanoparticle reduction and stabilization. Antioxidant activity was assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assays, revealing significant antioxidant potential. These Dc-AgNPs exhibit potential for use as antioxidant, antimicrobial and antiproliferative agents, making them valuable candidate for diverse therapeutic applications.
