Preface
The book contains scientific articles dealing with problems in physics, chemistry, and application of nanomaterials and supramolecular structures. It focuses on experimental investigations using a variety of modern methods and theoretical modeling of surface structures and physicochemical processes occurring at solid surfaces based on analytical approaches and computational methods. Special attention is focused on biomedical nanocomposites based on nanosilica and magnetite and their interactions with components of biosystems, as well as self-organizing of water– organic systems in nanopores of adsorbents, cells, and tissues; and immobilization of biopolymers, drugs, antioxidants at a surface of nanomaterials without the loss of their native properties. Techniques of chemical modification of nanomaterials and mesoporous nanostructured films, synthesis and studies of physicochemical properties of photo-active nanomaterials, nanotubes, and other materials are described. The results of investigations of supramolecular structures with biomolecules bound to a surface of highly disperse silica are generalized. The first part describes theoretical investigations of physicochemical processes occurring at a surface. A problem of interaction of electromagnetic radiation with surface excitations of a small particle ensemble at a solid surface was solved using the electrostatic approximation. The structural and total potentials of interaction of two quartz crystals separated by a nanosized gap were derived using Green functions with nonlocal Poisson’s equation. Conditions of initializing of ordered motion of nanoparticles along a surface under the effect of external fluctuations of different nature were described, as well as examples of highly efficient Brownian and molecular motors, photo-induced molecular and dip
