Transport of dyes in polyelectrolyte-surfactant hydrogels

Popis výsledku v původním jazyce

Polyelectrolyte-surfactant mixtures are progressive systems studied for their potential use in numerous applications in daily life including delivery systems for pharmaceutics. Mixing polyelectrolytes with oppositely charged surfactant ions in aqueous media typically leads to a strong association providing a simple route for constructing ordered materials with a great scientific and application potential. In this study, the combination of cationized dextran with sodium dodecylsulphate as surfactant was used for the preparation of two types of hydrogels. The diffusion of Nile red and Atto 488 dyes from their solutions in surfactant or NaCl into the hydrogels was monitored in time. The time development of the diffusion flows was used for the determination of basic transport characteristics of hydrogels. The diffusion of the probe dyes in prepared hydrogels was compared and discussed.
