RETRACTED ARTICLE: Air-stable superparamagnetic metal nanoparticles entrapped in graphene oxide matrix

Zero-valent metallic nanoparticles can exhibit superparamagnetism, due to quantum effects in magnetic nanomaterials, but their syntheses can be hindered by chemical instability. Here, the authors prepare air-stable superparamagnetic nanoparticles trapped between thermally reduced graphene oxide nanosheets.
