Table of Contents
The table of contents entry discrete plasmonic nanostructures comprising: 2, 3, 4 and 5 closely-spaced 15 nm gold
nanoparticles are seen as discreet bands on the gel image. The absorption visible spectra on the right panel show that the
magnitude of the red shift is directly proportional to the number of particles in the plasmonic structure.

SUPPORTING INFORMATION
Fig. S1 Time-dependent absorption changes of AuNPs suspension induced by Tris-Acetate. To 15 nm citrate-protected AuNPs (bottom
curve) Tris-Acetate (pH 7.4) was added to a final concentration of 4.5 mM and the spectra were recorded 0.7, 2.3, 4, 6, 8 and 10 min after
Tris addition.
