▎ 摘　　要

A simple, yet novel process was developed where magnetic graphene-CdS (Fe3O4-CdS/G) nanocomposites were prepared by a one-pot solvothermal route in which the reduction of graphite oxide (GO) into graphene was accompanied by the generation of CdS and Fe3O4 nanoparticles. The results of TEM and XRD studies indicate the formation of Fe3O4-CdS/G nanocomposites. Besides vibration sample magnetometry, fluorescence spectra and loading of doxorubicin (DOX) reveal that this new nanocomposite possesses good superparamagnet (44.85 emu/g), good fluorescent properties and a high loading efficiency (0.98 mg/mg). The efficient, stable, and water soluble nanocomposites are confirmed to be suitable for biomedical applications. (C) 2012 Published by Elsevier Masson SAS on behalf of Academie des sciences.
