The investigation of effectiveness of obtained SERS-substrates with metallic nanoparticles depend on the technical conditions of their preparation were performed. The parameters of the SERS-active substrates and experimental conditions of detection of extrasmall quantities of the chemical matters (Rhodamine 6G) and biological molecules (glucose, DNA, tumor cells) were optimized. The correlation between the effectiveness of the analytical response and the optical, structural and morphological properties of the nanostructured SERS-substrates and the methods of their functionalization were found. The differences in the vibrational spectra of the standard tumor cells and the cells, treated with the gold nanoparticles as the changes of the frequencies and the intensities of the different spectral regions (proteins, nuclear acids, lipids) were registered and analyzed.?
