The monograph addresses some of the problems of creating and studying "supramolecules" and membrane systems, the structure of monomers and polymers, the processes of immobilization of biologically active compounds (ALS) in mono- and multimolecular layers of monomers with the production of functional ultra-thin oriented membranes, supramolecular nanoscale systems for ALS transport; as well as the challenges of biotechnology in medical diagnostics.
