Lipo-nanosilver composites biogenerated using Artemisia abrotanum L. aqueous extract

Abstract

This work is focused on obtaining antioxidant materials based on liposomes and silver nanoparticles (AgNPs). The lipid vesicles labeled with chlorophyll a (as a spectral marker) were prepared by lipid thin film hydration method in a liquid crystal state. AgNPs were phytogenerated using an aqueous extract of Artemisia abrotanum L. (Southernwood), by using a “green” procedure. Three types of biohybrids based on liposomes and silver nanoparticles were prepared, and characterized by UV–Vis absorption and emission spectroscopy, DLS, and zeta potential measurements. The obtained bio-based materials exhibited good antioxidant properties estimated by chemiluminescence method.
