Hybrid vesicles : Magnetic nanoparticles (γ‐Fe 2 O 3 ) and quantum dots (CdSe/ZnS) can be entrapped in stable vesicles by emulsion processes. The hybrid vesicles (HVs) have distinct magnetic and fluorescence properties (see images; scale bars: 10 μm). Fluorescence detection allows magnetic manipulation and tracking of the HVs in vivo by both magnetic resonance and fluorescence imaging.
