Optimalization of techniques of microrheology for characterization of biopolymer hydrogels
 Dušenková, Alica ; Smilek, Jiří (referee) ; Sedláček, Petr (advisor)
The main aim of the bachelor thesis is optimalization of microrheological techniques for characterization of biopolymer hydrogels. Hydrogels, based on thermoreversible biopolymer agarose, were selected for these experiments. The influence of incorporated poly(sodium 4-styrenesulfonate) on structure and viscoelastic properties of agarose hydrogels was investigated through diffusion coefficient and MSD curves. Microrheological properties were studied by fluorescence correlation spectroscopy, by using fluorescent beads, which were embedded in hydrogel systems.

Insertion of polyelectrolyte additives in the hydrogel matrices - influence on the mechanical and transport properties
 Dušenková, Alica ; Klučáková, Martina (referee) ; Sedláček, Petr (advisor)
The main aim of the diploma thesis is to investigate the influence of incorporated polyelecrolyte additives on the mechanical and transport properties of hydrogel. Hydrogels, based on polyvinylalcohol, were selected for these experiments. Gelation of polyvinylalcohol can be induced physically or chemically. The aim was to investigate the influence of sodium alginate, sodium polystyrene sulfonate and sodium polyglutamate. Mechanical properties were studied by rheology, through viscoelastic properties. Transport properties were analyzed by using two methods: diffusion pair and fluorescence correlation spectroscopy.
