The technology of the preparation of high efficient nanostructured SERS substrates based on the functionalized metal nanostructured substrates, colloid nanoparticles, rough surfaces and films with metal (Au, Ag) nano-islands were elaborated. The investigation of the efficiency of prepared SERS substrates with metal nanoparticles in the dependence of technological parameters of colloidal synthesis and laser ablation were performed. The interconnection between the efficiency of analytic response, optical, structural and morphological properties of nanostructured SERS substrates and their functionalization methods was found. The practical testing of the prepared SERS substrates was carried out for the following biological objects: synthesized malignant tumor cell of the breast adenocarcinoma and ovarian carcinoma. The substantial spectral differences between the benign and malignant tumors, in particular, the changes in the frequency and intensity within the spectral range of proteins, nucleic acids and lipids were found. The state certification of the Laboratory of Optical Submicron Spectroscopy were performed in the field of optical measurements the properties of liquid and solid materials.
