Characterization of the structural composition of core/satellite nanoclusters via small-angle X-ray scattering on the example of Au84/Au16 nanoclusters: (A) 16 nm BSA-coated satellite NPs, (B) 84 nm citrate-stabilized core NPs, and (C) the final Au84/Au16 core/satellite nanoclusters. The building blocks of the clusters were fitted with a model for polydisperse spheres (red and violet solid lines). The clusters were fitted with a three-dimensional core/satellite model based on the ensemble-averaged scattering of 10 individual randomly assembled nanoclusters (blue solid line, Table 1, column 1).
