Study of reactivity in chemical transformations and supramolecular organization of natural polysaccharides of various origins. Investigation of solvation and dissolution of natural and modified polysaccharides, physico-chemical properties of solutions of polysaccharides and their mixtures with other polymers in a common solvent. Preparation and study of nanostructured biomedical materials on the basis of natural and modified polysaccharides.

 

Lines of research

 

• Development of synthetic methods for functional derivatives of polysaccharides (cellulose, chitin, chitosan); studies of their structure, chemical and physico-chemical properties, biological activity.
• Development and study of nanostructured polymeric systems based on natural polysaccharides and their derivatives for targeted delivery of biologically active compounds.
• Preparation of biomedical composite scaffolds (films, sponges, gels, nanofiber non-woven materials) on the basis of natural and modified polysaccharides and study of their properties.
• Investigation of complexation between chitosan and acidic polysaccharides (hyaluronic acid, alginic acid, carrageenan, cellulose derivatives).
• Studying solvation and dissolution of polymers and physico-chemical properties of cellulose solutions, its derivatives and mixtures of polymers in non-aqueous, aqueous, and water-salt solutions.
• Studying properties of physical thermoreversible gels based on natural polymers and their derivatives in aqueous and non-aqueous solutions.
