    • The extent of dendrimer adsorption depends on the substrate preparation. For example, we have observed dendrimer surface concentrations up to 50% higher on ozone-cleaned Au substrates.

    • note
    • The extent of dendrimer adsorption stability is a function of how the Au substrates are prepared and also on the age of the dendrimers. For example, we have noted that up to 25% of the dendrimer originally present desorbs during the first 20 h (although no desorption is observed after the first 20 h) of exposure to the ethanolic thiol solution if the dendrimer casting solution is very old (>6 months). Accordingly, the results described in this paper apply only to the specific conditions reported herein.

    • Ellipsometry is inherently model dependent, and whereas the ellipsometric model and attendant assumptions used here are reasonable and in accord with independently applied analytical methods, other models yielding different results could be used to fit the data.
