Synthesis, Shape Control, and Optical Properties of Hybrid Au/Fe3O4 “Nanoflowers”

Make like a leaf : The synthesis and characterization of a family of ???flowerlike??? Au/Fe3O4 nanoparticles is described, whereby Fe3O4 ???leaves??? adhere to a gold core (see image). The size and numbers of iron oxide domains can be adjusted flexibly by changing the proportion of the starting materials and the reaction time.
