Table 1. Structural Composition of Different Nanoclusters with Different Building Block Sizes and Material Compositions As Characterized by SAXS.
| Radius of Au core NPs/nma | 42.0 ± 3.4 | 42.0 ± 3.4 | 35.3 ± 3.9 |
| Satellite material | Au | Ag | Au |
| Radius of satellite NPs/nma | 7.5 ± 0.8 | 10.5 ± 1.2 | 7.2 ± 0.8 |
| Satellite coating | BSA | BSA | BSA |
| Core-to-satellite distance/nmb | 4.3 ± 0.3 | 4.0 ± 0.4 | 6.2 ± 0.5 |
| Number of satellites per coreb | 35 ± 1 | 11 ± 1 | 23 ± 1 |
| Corresponding Figures | 2B | 2D | S2D |
a
Variability in size is based on the standard deviation derived from a Gaussian distribution.
b
Variability in size of the satellites was omitted in the applied three-dimensional modeling of SAXS data. The given errors indicate the uncertainty of the ensemble-averaged core-to-satellite distance and number of satellites per core, respectively (see Supporting Information).
