Inside Cover: Multifunctional Uniform Nanoparticles Composed of a Magnetite Nanocrystal Core and a Mesoporous Silica Shell for Magnetic Resonance and Fluorescence Imaging and for Drug Delivery (Angew. Chem. Int. Ed. 44/2008)
Core–shell mesoporous silica nanoparticles which consist of a single magnetite nanocrystal core and a dye-doped mesoporous silica shell, are presented by T. Hyeon, W. K. Moon and co-workers in their Communication on page 8438 ff. These multifunctional nanoparticles can be used in simultaneous magnetic resonance and fluorescence imaging and can act as a drug delivery vehicle, thus having potential in cancer diagnosis and therapy.
