Objective: to gain new knowledge about the response of liquid crystal-controlled hybrid organic-inorganic plasmon nanostructures to the action of the electromagnetic field to predict new optical, transport and structural properties of these nanostructures. Research methods: theoretical analysis, comparison with experiment, computer modeling, mathematical data analysis. A modification of the Burreman analysis for the propagation of plane electromagnetic waves through an anisotropic metamaterial to obtain transmission matrices and propagation of such waves in this structure. It is taken into account that the eigenvalues ​​of the transfer matrix, which determine the transfer function, depend on the anisotropy. Details of beam propagation and negative refraction with the help of hyperbolic materials are clarified together with the theory of the effective medium of the transfer function based on the angular spectral decomposition of the beams. An analytical method for the study of plasmon structures with a swear filter is proposed and the dependences of reflectivity and transmittance are obtained, which can be used for the construction of devices based on Tamma plasmons. The conductivity of fragments of the DNA molecule, which are one of the receptors of the analyte in optical biosensors, has been studied. Fragments of DNA molecules were considered as one of the channels of metabolic electron transfer. The heterogeneity of complementary chains is taken into account. It allowed us to find the velocity of the electron excited in the conduction band of DNA and the current density it generates. The mobility of electrons in nucleic acid chains is estimated. It is shown that in the accepted simplest model of an unstructured nucleotide, taking into account the difference between complementary strands is impractical.
