Nanostructured films based on branched gold nanoparticles were obtained by self-assembly method. The possibility of controlling the film thickness in the range of 500 to 800 nm with preservation of their homogeneity and nanoparticle size (DSEM = 55 ± 12 nm) was shown. Position of localized surface plasmon resonance in absorption spectra of the film structures at λlspr = 595 to 600 nm is almost independent on the film thickness. The efficient surface-enhanced Raman spectroscopy substrates based on branched gold nanostructures were developed.
