Cover Picture: Cell‐Targeting Multifunctional Nanospheres with both Fluorescence and Magnetism (Small 5/2005)

The cover picture shows hela (human cervical carcinoma) cells that have been incubated with trifunctional nanospheres composed of CdSe/ZnS quantum dots, iron oxide nanoparticles, and folic acid (main picture: bright‐field image; inset: fluorescence image). The nanospheres combine fluorescence, magnetism, and cell recognition properties. For more information, please read the Communication "Cell‐Targeting Multifunctional Nanospheres with both Fluorescence and Magnetism" by D.‐W. Pang, W. Zhou, and co‐workers on page 506 ff.
