Ion-selective membrane with antimicrobial effect
 Gablech, Evelína ; Farka,, Zdeněk (oponent) ; Soukupová,, Jan (oponent) ; Drbohlavová, Jana (vedoucí práce)
This work deals with improvement of antimicrobial properties of commercial polymer membranes used in dairy industry for filtration of milk products such as whey. These membranes suffer from contamination caused by microorganisms present in milk during the filtration process. This biological contamination affects the life-time of the membrane and also filtration process itself. Thus, these membranes were modified with plasma treatment to incorporate amine functional groups for subsequent immobilization of silver and selenium nanoparticles to prevent the membranes from creation of biofilm of microorganisms. Antimicrobial activity of both types of nanoparticles and membranes with immobilized nanoparticles was determined against cell strains Staphylococcus aureus and Escherichia coli.
