• incubation of monodisperse, oleic acid-stabilized core particles (CdSe/CdS/ZnS-quantum dots, 5.5 or 7 nm; SPIOs, 11 nm) in chloroform with water-free 51CrCl3 or 65ZnCl2. The hydrophobic cores were then transferred into aqueous medium by encapsulation with a well-characterized amphiphilic polymer, poly[maleic
