title: Purification and magnetic interrogation of hybrid Au-Fe3O4 and FePt-Fe3O4 nanoparticles.
abstract: Purifying heterodimers: differential magnetic catch and release separation is used to purify two important hybrid nanocrystal systems, Au-Fe(3)O(4) and FePt-Fe(3)O(4). The purified samples have substantially different magnetic properties compared to the as-synthesized materials: the magnetization values are more accurate and magnetic polydispersity is identified in morphologically similar hybrid nanoparticles.
