Purpose: to establish mechanisms of interaction of conjugate systems with nanostructures to determine their sensory photovoltaic properties, complexation of drugs with important proteins and biopolymers, their immobilization on magnetosensitive nanostructures and directional transport, and detection of surface plasmon resonance metals of various shapes. It has been established that there is a complexation between antitumor drugs gemcitabine and doxorubicin with the transport protein albumin. In this case, the binding component is greater for hetero Associates with doxorubicin, for which electrostatic interaction is realized. When gold nanoparticles are added to the doxorubicin-albumin system, the binding constant decreases while maintaining the number of binding sites. It is established that in films of squarain, crocon, merocyanine dyes and their bases obtained by vacuum spraying and irrigation from solutions there is an interaction of identical one-dimensional conjugate systems due to the formation of different types of units, geometric parameters of which are determined by distribution and localization of charges groups. The interaction of dye molecules with C60 fullerenes in films obtained by simultaneous sputtering leads to the appearance of new absorption bands in the absorption spectra. The charge is transferred from dye molecules to fullerenes, which is accompanied by a change in the geometry and electronic structure of the complexes. The electronic levels of carbon nanoparticles in the complexes are shifted, and the energy gap is reduced. Product Description popup.authors Busko Tatiana O. Honcharova Oksana О. Lesiuk Andrii I.
