In the preparation, we varied the dose of gamma radiation from 20 KGy to 60 KGy. We found that the properties of hydrogel including gel content, swelling ability and mechanical properties were good on the radiation doses of 40 KGy. So we choose 40 KGy as the dose of gamma radiation. ...
A dual pH-/thermo-responsive hydrogel was designed based on a polyelectrolyte complex of polyacrylic acid (PAA) and norbornene-functionalized chitosan (CsNb), which was synergized with chemical crosslinking using bistetrazine-poly(N-isopropyl acrylamide) (bisTz-PNIPAM). The thermo-responsive polymeric...
Chitosan hydrogel beads were successfully prepared by the method of thermosensitive internal gelation technique. The prepared beads were spherical, smooth-surfaced and non-aggregated with a diameter of 1.7–2.1mm. The diameters of beads can be controlled and have a correlation with the initial drop ...

Zhao et al. [111] fabricated a cost-effective, biomass-derived and novel adsorbent by coating polydopamine on lanthanum-chitosan hydrogel (La-CS@PDA) which is rich in amine groups for the adsorption of phosphate in wastewater. Phosphate adsorption was enhanced by the diffusion structure of the ...
The present study proposes a simple yet effective method of cellulose coating onto chitosan (CS) hydrogel beads and application thereof as drug carriers. The beads were coated with cellulose dissolved in 1-ethyl-3-methylimidazolium acetate, an ionic liquid (IL) via a one-pot one-step process. ...
(GP) is a salt-based molecule that is used as an osteogenic supplement in cell culture systems and a sol-gel transition agent for chitosan thermosensitive hydrogel preparation. The Addition of GP to CS solution produces a neutral precursor solution of the thermosensitive hydrogel at room ...
The hydrogels fragments can quickly self-heal to form a single, ideally shaped hydrogel dressing that completely fills the wound area (Huang et al., 2018; Yu et al., 2021). Therefore, self-healing hydrogels with injectable properties have become one of the most attractive materials for ...
