Polyelectrolytes (PEs) are macromolecules that possess repeating units of ionizable groups
in addition to counterions. Polyelectrolyte complexes (PECs) emanate from the entropy …

One of the most promising pharmaceutical research areas is developing advanced delivery
systems for controlled and sustained drug release. The drug delivery system (DDS) can be …

Polyelectrolyte complex (PECs) hydrogels with high hygroscopicity modulation ability were
successfully prepared based on carboxymethyl chitosan (CMCS)/alginate. The swelling ratio …

Weak polyelectrolytes are relevant for a wide range of fields; in particular, they have been
investigated as “smart” materials for chemical separations and drug delivery. The charges …

Hydrogels are great systems for bioactive agent encapsulation and delivery. In this study,
polysaccharide blended whey protein isolate (WPI) based hydrogels were loaded with black …

This study investigated the combination of different proportions of cationic chitosan and
anionic carboxymethyl cellulose (CMC) for the development of polyelectrolyte complexes to …

In this article, the preparation of a gel electrolyte that consists of a polysulfide electrolyte with
xanthan gum (XG) thixotropic gel and TiO 2 nanoparticles (NPs) is reported for the …

The utilization of natural gum polysaccharides as the vehicle for drug delivery systems and
other biomedical applications has increased in recent decades. Their biocompatibility …

Escin is an amphiphilic and weakly acidic drug that oral administration may lead to the
irritation of gastric mucosa. The entrapment of escin into chitosan (CH)/xanthan gum (XG) …

A nontoxic multicarboxylic acid (critic acid) was incorporated into the chitosan/poly (ethylene
oxide) composite nanofibers by electrospinning. Critic acid was used to crosslink the …
