Bigels - Preparation and Characterization
 Mušková, Alexandra ; Krouská, Jitka (referee) ; Mravec, Filip (advisor)
This bachelor thesis deals with study of bigels, which are composed of hydrogel and oleogel. The aim of this work is to prepare and characterize bigels. Preparation of hydrogels was based on interaction between hyaluronan and cationic surfactant carbethopendecinium bromide. Oleogels were prepared by mixing a non-ionic surfactant (sorbitan monopalmitate) with sunflower oil. Individual bigels were prepared by mixing the various rations of hydrogel and oleogel, and were characterized using a fluorescence microscope and rheological measurements. Fluorescence observations were done on prepared samples using Nile Red, Perylene, HPTS, ATTO 655 and fluorescein. Rheological experiments show that pure oleogel is the strongest and most solid in comparison with bigels and hydrogels. The greater amount of oleogel in system is, the stronger bigel is.
