Original Abstract
This paper deals with fluorescence study of cetyltrimethylammonium bromide (CTAB) micellar solution after an addition of oppositely charged polyelectrolyte - hyaluronan. Two fluorescence probes solubilized in different region of micelles were used. The excitation and emission spectra, fluorescence intensity, steady-state fluorescence anisotropy and lifetime of probes in the samples were measured. It was observed that the interactions between cationic micelles and hyaluronan probably lead to binding micelles on hyaluronan chains and reduction of their size.
