N2 - We report a simple method for preparation of plasmonic nanostructures containing two, three, four, and five closely spaced 15-nm gold particles. The structures were separated from each other and purified to greater than 90 % by electrophoresis. The plasmon absorption spectra of the structures are redshifted with respect to the spectrum of gold nanoparticles not connected to each other. The magnitude of the redshift is directly proportional to the number of nanoparticles in the structure.
