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.
