Corresponding images as in Figure 7 for bioconjugates consisting of silver-stained HER81/gold nanorod conjugates incubated with (a) SKBR3 cells and (b) CHO cells. Care was taken to maintain the same acquisition parameters in both cases. The bioconjugates are accumulated at the cell membranes of SKBR3 cells where HER2 is localized. As expected, no such accumulation takes place in the case of HER2 negative CHO cells.
