In this talk I will present the results of several experiments on self-assembled silver nanoisland films. By measuring surface-enhanced Raman spectroscopy (SERS) spectra of rhodamin 6G and bacteriorhodopsin we have shown that these films can serve as SERS substrates.
Using field imprinting technique we have obtained single nanoislands and characterized resonant scattering properties of single particles by means of dark-field microscopy. The AFM measurements allowed us to obtain information about the shape of the respective silver nanoislands.
