Aqueous Cymbopogon citratus Extract Mediated Silver Nanoparticles: Part I. Influence of Synthesis Parameters, Characterization, and Biomedical Studies

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(5), P. 328 - 328

Published: Feb. 20, 2025

This study explores the green synthesis of silver nanoparticles (AgNPs) using Cymbopogon citratus (lemongrass) extract as a reducing agent. Synthesis was confirmed by color change (light yellow to dark brown) under optimal conditions: 1.50 mM nitrate, 3.5% v/v extract, at 100 °C, with pH 9, and for 60 min. The AgNPs exhibited spherical morphology, hydrodynamic diameter 135.41 ± 49.30 nm, zeta potential -29.9 1.4 mV, crystalline structure, minimal aggregation. showed significant antibacterial activity, particularly >20 µg/well, zones inhibition varying bacterial strain. In vitro studies demonstrated anti-inflammatory, antidiabetic (α-glucosidase α-amylase inhibition), antioxidant activities, outperforming plant nearing standard efficacy higher concentrations. Cyto-toxicity indicated that were less toxic than doxorubicin but concentration-dependent effects on cancerous non-cancerous cells. Eco-toxicity assays revealed acutely controls posed risks prolonged exposure. work highlights eco-friendly their in biomedical applications, demonstrating activities.
