Abstract

Lecithin liposomes were studied by transmission electron microscopy (TEM), selected‐area electron diffraction (SAED), IR, and GC‐MS. Results indicate that titanium dioxide (TiO₂) nanoparticles can gain access into lecithin liposomes during sonication and the lecithin liposomes can be effectively decomposed upon illumination with near‐UV light.
