POLYCATION-SURFACTANT INTERACTIONS AND THE FORMATION OF HYDROGELS WITH INTERNAL NANOSTRUCTURE

Popis výsledku v původním jazyce

Oppositely charged polyelectrolytes and surfactants can form under specific conditions hydrogels containing micelle-like nanostructures. Due to its hydrophobic core, these structures are capable of solubilizing hydrophobic substances within hydrophilic soft solid matrix. Such hybrid materials can be subject of interest for medical applications. In this study, interactions between cationic dextran and sodium dodecylsulphate were studied and conditions of gel formation investigated. Using the technique of fluorescence probe, phase behaviour was analyzed and region of the gel phase separation detected. Solubilization of hydrophobic dyes confirmed the formation of micellar domains. The gel formation was affected by ionic strength of gelling solutions.
