Ultra-sensitive diagnosis of orthotopic patient derived hepatocellular carcinoma by Fe@graphene nanoparticles in MRI†
Abstract
We synthesized core–shell structured Fe/G-PEG NPs composed of an Fe core and a PEGylated graphene, which exhibited superior stability against oxidation, good water dispersity, low cytotoxicity and high magnetic performance. These advantages ensure them as candidates for ultra-sensitive contrast enhanced magnetic resonance imaging agents in vivo.
