The rheological properties of hydrogels prepared by physical interactions between oppositely charged polyelectrolyte and surfactant in micellar form were studied. Specifically, hyaluronan was employed as a negatively charged ...

Huminové kyseliny jsou považovány za látky s tzv. supramolekulární strukturou, jež je základem jejich unikátních vlastností a fungování v přírodě. Naše studie potvrdila, že již malý přídavek těchto látek do agarozových ...

Interaction between polyelectrolyte and oppositely charged surfactant leads to a formation of a hydrogel with micellar nanodomains. The main focus of this work was to monitor and study how pH and its changes affect mainly ...

This study introduces an original concept in the development of hydrogel materials for controlled release of charged organic compounds based on semi-interpenetrating polymer networks composed by an inert gel-forming polymer ...

PVA hydrogels can be formed via physical crosslinking (e.g. by cyclic freezing/thawing of aqueous polyvinyl alcohol solutions) or with a chemical cross-linker. Physical crosslinking is more useful for biomedical applications ...

Nowadays, hydrogels are found in many applications ranging from the industrial to the biological (e.g., tissue engineering, drug delivery systems, cosmetics, water treatment, and many more). According to the specific needs ...
