High-resolution ultrasonic spectroscopy for studying of polyelectrolytes and surfactants

Popis výsledku v původním jazyce

Hyaluronan is a well-known biopolymer synthesized in various organisms including the human body. It is formed by a repeated basic dimeric unit composed of glucuronic acid and N-acetyl-glucosamine. Due to its biological origin, biocompatibility, non-immunogenicity, and biodegradability, hyaluronan has found various applications in the fields of cosmetics and medicine. Due to the presence of carboxylic groups in its backbone, hyaluronan behaves in aqueous environments as a polyelectrolyte. At physiological pH values, hyaluronan possesses negative charge and is thus capable of attractive electrostatic interactions with positively charged partners. Thus, interactions between hyaluronan and cationic surfactants have been intensively studied as a specific example of a broader class of polyelectrolyte-surfactant interactions. The binding of surfactant to hyaluronan was detected for surfactants with an alkyl chain consisting of at least ten carbon atoms (1, 2). Interactions between hyaluronan and the cationic
