Utilization of fluorescence spectroscopy for studying of the interactions in dried systems of biopolymer and hydrophobic species

Paper in proceedings (conference paper)

Molecules of biopolymers such as hyaluronan or carboxymethylcellulose have hydrophilic character. On the other side the chains of these natural compounds contain also hydrophobic areas. These parts are often protected by water molecules that are probably highly organized. The interactions between native hydrophilic biopolymers and hydrophobic solutes were studied using the method of fluorescence spectroscopy. It was observed, that drying of the systems open up the binding sites for hydrophobic compounds. After system rehydration the hydrophobic solutes are locked up on the chain of biopolymer by the molecules of water.
