    • The role of cluster size on the diffusion process was studied using 130-Å gold colloidal particles and not silver, since we are yet to standardize an experimental procedure for reproducibly obtaining larger/smaller-sized silver colloidal particles.

    • Optical absorption spectroscopy measurements were carried out on a Hewlett-Packard 8452 diode-array spectrophotometer operated at 2-nrn resolution. The quartz substrate for optical absorption measurements was cut in such a way as to fit in a snug, vertical position in the spectrophotometer quartz cuvette. Spectra of the film were recorded during immersion in the hydrosol and in air after evacuating the cuvette and thoroughly washing and drying the film prior to measurement.

    • If one neglects the optical anisotropy in long-chain fatty amine molecules, a reasonable assumption given that the thermally evaporated amine molecules are expected to be fairly disordered, the refractive index of the amine film would be close to 1.5. See, for example, the following. Paudler, M.; Ruths, J.; Riegler, H. Langmuir 1992, 8, 184. Honig, E. P.; De Konig, B. R. Surf. Sci. 1976, 56, 454.

    • In situ QCM measurements were made on a 150-Å-thick thermally evaporated amine film on a 10-MHz quartz crystal. Measurements were made as a function of time of immersion of the amine film in a silver hydrosol at pH = 8.5 using an Elchema model 702 electrochemical quartzcrystal nanobalance. The damping of the resonance frequency due to water was calculated to be 1750 Hz (Wang. J.; Frostman, L. M.; Ward, M. D. J. Phys. Chem. 1992. 96, 5224) and was subtracted from the measured in situ frequency. This difference was then converted to a mass loading using the Sauerbrey formula (ref 12). The mass uptake due to cluster incorporation was estimated from the change in weight of the dry cystals after removal from the silver sol.
