Development of track membranes applications in Poland

In the work Particle Track Membranes (PTMs), a microfiltration material manufactured by using heavy ion beams from cyclotrons, are characterized. results of radiation resistance measurements for PTMs made of different polymeric films as: PET, PC, PP are given. PTMs have been applied in several fields including biomedicine and biotechnology. In the first case dispensable syringe filters and multilayer medical dressings have been worked out. If pore sizes of PTMs in these products are 0.2 μm they become a barrier for microorganisms including bacteria. Applications of PTMs in a dynamic filtration device with rotating cylinder has been investigated. For pilot testing microfiltration of biotechnological suspensions with yeast cells has been used. From economical point of view obtained microfiltration results could be acceptable. (author)
