pH-sensitive keratin-based polymer hydrogel and its controllable drug-release behavior

New Developments in Medical Applications of Hybrid Hydrogels Containing Natural Polymers

New trends in biomedical applications of the hybrid polymeric hydrogels, obtained by combining natural polymers with synthetic ones, have been reviewed. Homopolysaccharides, heteropolysaccharides, as well as polypeptides, proteins and nucleic acids, are presented from the point of view of their ability to form hydrogels with synthetic polymers, the preparation procedures for polymeric organic hybrid hydrogels, general physico-chemical properties and main biomedical applications (i.e., tissue engineering, wound dressing, drug delivery, etc.).

Preparation of keratin/chlorhexidine complex nanoparticles for long-term and dual stimuli-responsive release

Nanoscale polyion complex formation via the electrostatic complexation of a polyelectrolyte and a charged drug is the most convenient method for building a drug delivery system that simultaneously realizes the carrier preparation and drug embedding.
