the chemical reduction rate, but also on the intermicellarexchangerate. Furthermore, intermicellar exchange causes the accumulation of slower precursors inside the micelles, which favors chemical reduction. As a consequence, slower reduction rates strongly correlate with the number of reactants in
this confined media. On the contrary, faster reduction rates are limited by the intermicellarexchangerate and not the number of reactants inside the micelles. As a result, different precursor proportions lead to different sequences of metal reduction, and thus the arrangement of the two metals in the
nanostructure can be manipulated.
