The dissertation is devoted to the research of the influence of morphology in systems with high - conductivity nanostructures on the resonance response of localized surface plasmon in real applications, and also to the research approaches for the regulation of wave position of localized surface plasmon resonance (LSPR). The relevance of the work is explained by the widespread use of high-conductive nanostructures for sensory applications and to increase the sensitivity of optical measurement methods. Currently, the registration of LSPR response of high-conductivity nanostructures is used in sensory analysis of materials, registration of analyte molecules, enhancement of fluorescent properties of materials. Also LSPR methods can be effective in developing new treatments, can solve many problems of clinical diagnosis, environmental monitoring and are widely used in biochemical research and biomedical applications, such as labels in real time, or as a transport of drugs. It should be noted that one of the important advantages of using nanoparticles in sensorics is the fact that this method is non-destructive and non-invasive. Therefore, the research and study of the morphology influence on the LSPR-properties of metal nanostructures attracts much attention in modern fundamental and applied physics, molecular plasmonicsin particular. Nanostructures of high-conductivity metals are most often used in researches, in which the phenomenon of LSPR occurs - such as gold, silver.
