  • Synthetic polymers fulfill many functions in biotechnology and medicine. In cell culture technology and tissue engineering they provide the surfaces to which cells may attach. Cross-linked polymer networks are used for drug delivery and cell encapsulation. Polymer-based porous membranes can be used to shield implanted cells from the immune system of the host, while allowing for the exchange of nutrients and metabolic waste products thus keeping the cells alive and functioning.

  • A thermodynamic model for heterogeneous mixtures involving multi-molecular sorption is proposed. Some complex relationships between sorption potential, diffusion, sorption kinetics polymer network change kinetics, chemical affinity energy of internal changes and physico- chemical properties of polymer network are obtained. This model has interpreted some experimental results of fluid sorption in polymer network. Proposed model may be also used for study of other problems in heterogeneous mixture of fluid and polymers.
