In this diploma thesis has been studied system of hydrogels based on interaction between polyelectrolyte and surfactants, especially their solubilizing properties. As a surfactant was used ionic cationic cetyltrimethylammonium bromide (CTAB). As a polyelectrolyte was chosen native anionic hyaluronan with various molecular weight - 0,3; 0,9; 1,6 MDa and with different concentration - 2%, 4%, 6% wt. Solubilization experiments were realized with hydrophobic dye sudan red G. The whole system was prepared in the simpliest model system of physiological solution 0,15 M NaCl and in water. At the prepared gels was investigated their stability, influence of the environment, molecular weight and concentration on solubilization. Gels were prepared in rate hyaluronan-surfactant 1:1. The purpose of this diploma thesis was to find and optimize the appropriate procedure for determining solubilization capacity by using UV-VIS spectrophotometry.
