First published online : 23 Apr 2013
We describe an environmentally friendly, top-down approach to the synthesis of Au89Fe11 nanoparticles (NPs). The plasmonic response of the gold moiety and the magnetism of the iron moiety coexist in the Au89Fe11 nanoalloy with strong modification compared to single element NPs, revealing a non linear surface plasmon resonance dependence on the iron fraction and a transition from paramagnetic to a spin glass state at low temperature. These nanoalloys are accessible to conjugation with thiolated molecules and they are promising as contrast agents for magnetic resonance imaging.
