The purpose of our work was to obtain "magnetoliposomes" by enwrapping dodecylbenzensulphonic acid-stabilized Fe3O4 nanoparticles in a phospholipid lecithin-cholesterol matrix. Generated liposomes were observed under polarized light microscopy. We used different types of lecithin (vegetal and/or animal). For studying the permeability of the membrane, we performed conductivity measurements for both the pure liposomes and the magnetoliposomes in an aqueous medium.
