The electron-molecular conformational transformations of nanocomplexes and the ability to improve the efficiency of antineoplastic drugs was studied. The analysis of the mechanisms of antitumor action of drugs with carbon and metal nanostructures on the properties of the solvent and dose radiation exposure was performed. 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.
