摘要：

(Chemical Equation Presented) Heavy lifting: Dumbbell-shaped Au-Fe 3O4 nanoparticles are made biocompatible and suitable for attachment to A431 cells. The particles are magnetically and optically active and are useful for simultaneous magnetic and optical detection (see picture). The Au-Fe3O4 nanoparticles are promising as a new type of multifunctional probe for diagnostic and therapeutic applications. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
