Current Subject Matter Research

The subject matter of the lab focuses on developing different ways of obtaining membranes as well as examining them. We develop flat membrane, 3D scaffolds and also membranes hollow fibers. All of these membranes are designed for chemical, separation, biotechnology and biomedical applications.

Flat membranes from the lab can be divided into three main types. The first one is wide porous membranes type 3D which are intended to cultivate cells. They have been successful in the cultivation of hepatocytes and chondrocytes. Chrondrocytes cultivated on these membranes (in cooperation with the Centre of Postgraduate Medical Education) were successfully implanted in rabbits’ knees. These membranes have a unique construction due to two types of pores, macropores as a place for developing cells and micropores which provide transport for cellular metabolites.

Other types of flat membranes can be used to develop dry immunochemical and immunoenzymatic tests. These membranes are preliminarily chemically or physically modified on the surface, for instance with low temperature plasma. The surface which is functionalized in such a way enables effective bonding of enzymes, antibodies and analytical compounds. Flat membranes on the cellulose medium are used to obtain dry tests for the analysis of media containing suspension and precipitates such as blood, fruit and vegetable juices or different types of sewages. There is a special profile for the filtration depending on what the membranes will be intended for.

The most recent part of the research is developing composite membranes. Such membranes consist of portable layers of polymers, for instance polysulfon or polyesters with different porosity, thickness and with different types of surface as well as active layers, for example hydrogelic one which are connected to the surface of the portable layers. Such membranes can be used to cultivate skin or epidermis cells. Ultimately they are to serve as allogenic patches to cure massive loss of skin or epidermis. These membranes are characterized by the possibility of convenient detachment of the gel layer from the polysulfone layer.

Hollow fibers are developed in two versions: basic one with smooth walls and with more advanced inner surface (folded walls).

Membranes with such parameters can be developed depending on the needs. Membranes with more developed inner surface can have better hydraulic parameters in comparison with smoth one. They may prove highly valuable in encapsulation or developing bioreactors. A unique method of enlarging pores in the ready hollow fibers is being developed, which enables developing membranes with controlled and programmed cut-off points. Such membranes facilitate selective functioning of proteins, in particular plasma.
