25. 1s signals increased and decreased, respectively.
26. Advancing contact angles are 68±2° and approximately 20° before and after adsorption of G4 assemblies onto the CD SAMs, respectively.
27. 4- couple was used, the charge-transfer resistance decreased from 38 to 3 kΩ, because the electrostatic attraction by the dendritic core facilitates the oxidation/ reduction at the electrode surface.
28. The apparently slow adsorption as shown in the first parts of Figure 2 a upon increase of the G4 concentration can be attributed to diffusion of G4 in solution, since the adsorption in the SPR setup leads to a depletion of the liquid above the surface of > 100 μm, while diffusion in solution over such distances probably takes more than 1 s.
