Shape and composition of Fe3O4@GdPB NPs.
Notes: (A) Transmission electron microscopy image of Fe3O4@GdPB NPs. (B) Representative energy-dispersive X-ray spectrum of Fe3O4@GdPB NPs. The composition was derived by built-in software from the attribution of the electronic energy profile for Fe, K, and Gd.
Abbreviation: Fe3O4@GdPB NPs, composite iron oxide-gadolinium-containing Prussian blue nanoparticles.
