Originální abstrakt

This work is focused on ionic interactions between oppositely charged polyelectrolytes and surfactants which can – under proper conditions – lead to formation of physical gels. Surfactants form micellar structures enabling to solubilize hydrophobic substances in the otherwise aqueous environment of the gel. Resulting materials can find use in the formulation of delivery systems, e.g. hydrophobic drugs especially in topical applications. Main aim of this work is to study rheological properties and preparation techniques of materials, that are formed from positively charged polysaccharides (chitosan, cationized dextrane) and negatively charged surfactant (SDS). The presence of hydrophobic nanodomains was tested by solubilization of hydrophobic dyes (e.g. Oil red O, prodan).
