Аннотация:New hybrid nanosystems based on biomolecules of cholesterol and its heteroatomic analog thiocholesterol including nanosized silver particles of d = 5.0 ± 0.5 and d = 2.5 ± 0.5 nm, correspondingly, have been obtained by two-phase chemical synthesis. Ordered 1D, 2D, and 3D structures including silver nanoparticles were formed on different support surfaces by removing of inert solvent from triple metal/ligand/solvent system and by cooling of binary metal/ligand system from isotropic state to liquid crystalline mesophase. The microstructure and composition of the hybrid nanosystems were characterized by Fourier transform infrared spectroscopy, UV–vis spectroscopy, and transmission electron microscopy.
