The aim - іs to analyze the nature of the interaction of laser radiation with nanoobjects that demonstrate the resonant response and to establish the conditions under which the formation of a forced light pressure force or an increase in the gradient force acting on selectively absorbing nanoparticles is possible. Theoretical and experimental studies of the motion of nanoparticles in gradient light fields both in vacuum and in liquid media of different nature. Development of technology for the formation of 1D, 2D waveguide FC structural basis of polymer nanocomposites of woofer metals and metal oxides. Fabrication of structures by holographic lithography and their characterization (thickness, amplitude of modulation of refractive index, surface characteristics). The research method is a description of the interaction of nanoparticles with laser radiation and their motion by methods of electrodynamics, quantum mechanics, classical mechanics. Finite Difference Time Domain (FDTD) method, holography methods. The important role of plasmon excitation in the formation of the light pressure force on nanoparticles has been established. According to the available literature, the components of the force along and across the direction of propagation of a light wave significantly (within several orders of magnitude) depend on the shape of the particle, as well as on its orientation relative to the direction of incident radiation. Literature sources describing the interaction of rare earth atoms with the laser radiation field indicate the possibility of organizing a closed or almost closed cycle of interaction with the field, which is important for laser control of lanthanide motion. The propagation of an electromagnetic wave by the structure of synthetic opal by the finite difference method in the time domain is calculated.
