Chitosan oligosaccharide (COS), a time-dependent antimicrobial carbohydrate, is found
antifungal active with a short duration of action due to excessive solubility. We attempted to …

Cryogel was synthesized through cryogelation of methacrylated carboxymethyl chitosan
(mCMC) and poly (ethylene glycol) diacrylate (PEGDA) precursors by photopolymerization …

Original pH sensitive cryogels, based on two biodegradable natural polymers chitosan (CS)
and 2-hydroxyethylcellulose (HEC), were obtained via cryogenic treatment of semi-dilute …

Chitosan-based cryogel particles were synthesized using the inverse Leidenfrost (iLF) effect,
with glutaraldehyde employed as the cross-linker. The resulting cryogels exhibited a sponge …

Biodegradable macroporous hydrogels were prepared using a biodegradable crosslinker
based on chitosan derivatives. The chitosan crosslinker was synthesized through the …

Massive hemorrhage caused by accident or surgery is a major factor in accidental death. In
addition, bacterial infection is also an important threat after bleeding. Cryogels with …

Wound dressing is a kind of significant artificial materials for protecting injured tissues and
promoting wound healing. However, fabrication of antibacterial wound dressing usually …

We report a new 3D nanocomposite cryogel combines the advantages of cationic starch
(Cs), nanofibrillated cellulose (NFC) and silver nanoparticles (Ag NPs). Cs was the main …

Chitosan (CS)-based drug delivery systems (DDSs) are often stabilized by chemical cross-
linking. A much more friendly approach to deliver drugs in a controlled manner is …

Inherently antibacterial polycations have been of interest in the pursuit of overcoming
antibiotic resistance. In this study, we have prepared a new cryogel system incorporating …
