Objects of research: Nanostructured materials and low-dimensional systems. Methods of research: theoretical calculations, computer, analytical and full-scale simulation, the technology of PBM (Proton Beam Writing). The results of fundamental theoretical and experimental studies of nanocomposites, low-dimensional systems and materials are presents. The principles of practical application of these results, particular, for creation of materials with controlled optical response, development of new methods of antiviral therapy, purification of liquids; antiviral effect of Au-SiO2 complexes of nanoparticles against adenoviruses was demonstrated. In addition, the use of irradiation by high-energy protons to create elements of microelectronics based on germanium was propose. Theoretical results includes. The configurationally resonances of light absorption by the thin films with metallic nanoparticles are calculated. Physical bases of interaction between viruses and nanoparticles of different composition and form, as well as with nanostructured surfaces, have been developed. On the example of a model of two isotropic nanoparticles with a giant linear polarization and a stabilizing nonlinear polarizability of the third order, it is shown that the van der Waals forces essentially increase at small distances and the exact account of nonlinearity does not lead to repulsion. The theory of van der Waals interaction of finite-size nanowires and systems of boson atoms in a low-density mode are constructed. Experimental results includes. Light focusing was performed using binary amplitude modulation through samples of a strongly dispersing medium; The developed and optimized methods and modes of modification of semiconductors by irradiation by light ions have been developed and their electrophysical properties have been investigated. The research results are implemented: in the educational process of the Institute of High Technologies and the Faculty of Psychology of the Kyiv National Taras Shevchenko University.
