Аннотация:Organized composite bio-organic/inorganic nanostructures have been formed by hetero-phase and interfacial synthetic methods and via self-assembly. It was found that system dimensionality in relation to the energy balance determine specific features of structure organization in metallic and magnetic nanostructures formed using biogenic polyamine as a polydentate ligand. Theoretical considerations and modeling showed that the energetic balance between electrostatic repulsive interactions of structure-forming colloid components of the material and attractive forces resulted from the chemical bonding of components via bridge multidentant ligand polyamine molecules had substantial effect on the morphology of the formed nanocomposite structures. Those findings give possibilities for efficient control of structural-functional characteristics of that type of nanomaterials. The described synthetic strategies and methods are relatively simple, rapid, inexpensive and allow large-scale and parallel preparation of organized functional nanomaterials at ambient and ecologically-friendly conditions that makes them potentially promising for applications in various fields of modern materials science and nanotechnology.
