Normalized pair-distance distribution functions p(r) of anomalous and conventional components of the PEGylated AuNPs. Dotted lines represent the p(r) for the anomalous part (gold core). Solid lines represent non-anomalous scattering from all atoms in the sample far from the absorption edge. Red is for 2 kDa PEG- and blue for 5 kDa PEG-coated AuNPs. The gold core has the same size in both cases.
