Synthèse Verte Des Nanoparticules D’argent A L’aide Du Marrubium Vulgare

Abstract

Nanotechnology, a rapidly expanding multidisciplinary field, offers new perspectives for the synthesis of nanomaterials with rmarkable properties. Amongthese nanomaterials, silver nanoparticles (AgNPs) have attracted considerable interest due to theirnumerous applications in biomedical, pharmaceutical, and industrial fields. The green synthesis of silver nanoparticles using plant extracts represents an environmentally friendly and cost-effective alternative to conventional synthesis methods. This study focuses on the biosynthesis of silver nanoparticles from the aqueous extract of white horehound (Marrubium vulgare). The characteristic peaks obtained by UV–Visible spectroscopy at 448 nm confirmed the formation of AgNPs. Furthermore, this analys is highlighted the influence of different parameters, particularly the concentration of silver nitrate, on the synthesis process. FTIR analys is revealed the functional groups involved in the reduction and stabilization of the nanoparticles, especially the O–H, C=O, and aromatic C=C groups of the polyphenols and flavonoids present in the plant extract. The study also demonstrated that a concentration of 1 mM represents the optimal condition for obtaining stable and homogeneous nanoparticles. These results confirm the potential of white horehound as an effective biological source for a simple, cost-effective, and environmentally friendly green synthesis
