Image of FIG. 1.
FIG. 1.

[(a)–(b)] TEM images of the initial NAC film, deposited at , showing (a) the fractal morphology and (b) the nanoscale clusters. [(c)–(f)] Series of TEM images of NAC films coated with different amounts of Ag, equivalent to metal film thicknesses of (c) 1, (d) 3, (e) 5, and (f) .

Image of FIG. 2.
FIG. 2.

Histograms of nanoparticle size for equivalent Ag film thicknesses of (a) 1, (b) 3, and (c) . (d) Shows a plot of mean particle size as a function of equivalent Ag film thickness.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Raman spectra from drops of the R6G solution on NAC substrates with Ag coatings of 0, 1, 2, and . A linear photoluminescence background has been subtracted, and the spectra have been offset for clarity. (b) Florescence spectra from BSA-FTIC on a series of different substrates. (i) Flat amorphous carbon, (ii) untreated NAC, (iii) equivalent Ag coating, (iv) Ag, and (v) Ag. Inset: Fluorescence image of a protein coated array of NAC patches, patterned onto a flat amorphous carbon surface.
