摘要
A dopamine-PEG based ligand is synthesized and used to stabilize monodisperse 9 nm Fe3O4 nanoparticles in physiological conditions and against non-specific uptake by macrophage cells. Such stable nanoparticles can be used to enhance the efficiency in target-specific drug delivery and to increase the signal-to-noise ratio in magnetic resonance imaging (MRI).
