The paper describes the fabrication of random and ordered gold nanostructure arrays (NSA) of different
morphology using island film thermal annealing and nanoimprint lithography techniques. Structural
parameters of obtained NSA were investigated using atomic force microscopy method. Spectral characteristics
of obtained NSA were studied in air atmosphere, and NSA light extinction spectra exhibited an expressed
plasmon peak. Spectral position of localized surface plasmon resonance can be tuned depending on
geometrical parameters of nanostructures, which is an important factor for resonant investigation methods
of various types of molecular structures. Proposed technological approaches can be used to implement the
resonance fluorometry in electromagnetic field of nanostructures (surface-enhanced fluorescence) method
and in chemical and biosensors based on localized surface plasmon resonance.
