In this study, a multifunctional graphene based nanohybrid, termed as GN/Fe 3 O 4 /PF127, is engineered via a facile one-pot process consisting of simultaneous reduction of graphene oxide/Fe 3 O 4 and subsequent assembly of Pluronic F127 (PF127) onto graphene nanosheets (GNs). The unique aromatic and planar structure of GNs allows the attachment of multiple functional components including MRI contrast agent (Fe 3 O 4 nanoparticles) and an aromatic anticancer drug like doxorubicin (DOX), as well as PF127 coating which imparts physiological dispersivity and stability to the nanohybrid. The successful assembly process is revealed by TEM observation, size and FITR monitoring. In contrast with the primitive graphene or its oxide derivative, the resulting GN/Fe 3 O 4 /PF127 nanohybrids have shown high biological dispersion and MRI effect for diagnosis due to the incorporation of superparamagnetic Fe 3 O<...
