The object of the research is nanosystems consisting of simple metal nanoparticles with different stabilizers/sizes and bioobjects of different types. The subject of research is the interactions in biosystems with nanoparticles, in particular near-field interactions as a basis for antipathogenic action of nanoparticles. The purpose of this work is to control the physicochemical parameters of nanoparticles and to develop a theoretical model of the interaction of nanoparticles with the surface of microbes. The research methodology includes the use of spectroscopic methods for analyzing the properties of colloidal solutions and theoretical methods for studying the physics of nanosystems. Results and novelty of the work. Together with other co-executors of the Project, protocols for the synthesis of gold and silver nanoparticles stabilized with tryptophan and sodium dodecyl sulfate were improved, and protocols for the synthesis of nanoparticles of various sizes were developed on their basis. A model of interaction of nanoparticles with the surface of a microorganism has been developed theoretically, which highlights the selectivity of the effect of nanoparticles on microorganisms. Key words: nanoparticles, stabilizer, synthesis, near-field interaction, nanosystems. Product Description popup.authors Lysenko Volodimir Sergiyovych popup.nrat_date 2022-11-03 Close
