Figure 2

Control experiments to show the importance of the complimentary chemistry and the stable nature of the triazole ring. The figure shows (a) the procedure for the first layer nanoparticle deposition as described in the text sans for azide termination of the gold substrate and washing; (b) the same procedure for first layer nanoparticle deposition sans for azide termination of the gold substrate (but washed and sonicated in methanol); and (c) the procedure as written (for reference, with all steps included). Part (d) shows an AFM image of a single layer of nanoparticles of 80 nm in diameter attached by “click chemistry” to the same substrate.
