The paper presents the obtaining of liposomes containing titanium dioxide nanoparticles by using the ultrasonication method. Natural lecithin and titanium dioxide doped with Au+ ions were used for obtaining the liposome micro/nanocapsules and these were analyzed by scanning electron microscopy, transmission electron microscopy, and energy-dispersive X-ray spectroscopy. Generally, the liposomes have not a higher uniformity, being formed by agglomerated capsules with various diameters up to 500 nm, as is revealed by SEM and TEM analyses. These liposomes contain titanium dioxide nanoparticles as is demonstrated by EDS analysis. The composition of liposomes containing titanium dioxide was: 25.5-49% lecithin, 1.3-2% TiO2, and 48.8-73.2% water (on the basis of EDS analysis).
