Figure 3.
HRTEM and corresponding FTT images of size-selected magnetite–gold NPs: MNP-15 (A, C) and MNP-25 (B, D). Fe3O4 and Au indices are marked yellow and red, respectively. The [111] and [200] crystallographic directions of Fe3O4 and Au register to each other. The NPs are viewed along their [011] direction.
