Abstract

The development of modern bio-nanoelectronic technologies requires new hybrid organo-inorganic systems that have a specific functional purpose and allow work in the tissues of living organisms. The practical realization and scientific study of a hybrid two-component system in the form of DNA molecule fragments and nanoparticles of biocompatible ceramics was the goal of this work.
The interaction of a DNA molecule with nanoparticles of a solid solution of the composition ZrO2–3mol% Y2O3 (YSZ) was studied using Raman scattering and transmission electron microscopy. Samples of YSZ oxide and hydroxide were investigated in triplicate at room temperature using LabRAM HR Evolution Horiba spectrometer and JEM 200A instrument.
The effect of the force field of the surface of YSZ nanoparticles on the optical properties of the DNA molecule in the TRIS buffer solution was shown. The effects of increasing the intensity of spectral lines in the long-wavelength region 250 – 660 cm-1 (254 cm -1, 322 cm -1, 470 cm -1, 663 cm -1). suppressing the intensity of spectral lines in the shortwave region 600 – 3300 cm -1 (604 cm -1, 917 cm -1, 951 cm -1, 1256 cm -1, 1302 cm -1, 2767 cm -1, 3180 cm -1, 3241 cm -1, 3285 cm -1), as well as shifting lines 519 cm -1, 917 cm -1, 1048 cm -1, 1547 cm -1 and 1639 on 40-60 cm-1 in the shortwave region are established.
From the standpoint of the theory of wave processes, a qualitative description of the detected Up-conversion effect was done. An assumption about the potential applicability of the YSZ nanoparticle surface – DNA nucleotide interfaces as a heterodyne frequency converter in molecular- and bio-electronic devices was made.
