    • The increased number of amide bonds in G4-SH(100%) compared to G4-NH2 (188 vs 124) is almost quantitatively compensated for by the increased size of the molecule (ca. 5.5-6.0 nm vs 4.5 nm). Thus, the intensity of the amide peaks should be similar for these monolayers (provided the fractional surface coverage is the same for both). A similar argument applies to G4-SH(20%) and G4-SH(10%).

    • Elemental analysis showed that C/H/N ratios are correct within ca. 15% error, which points to the likely presence of some impurities in the samples. This error is passed on to the calculated values of the Au/dendrimer ratio. The error is, however, much smaller than the changes of Au/dendrimer ratio between the samples and, therefore, does not invalidate our conclusions.
