In this paper, we report the synthesis and evaluation of a polyvinyl alcohol/chitosan
(PVA/chitosan) hydrogel incorporated with green synthesized cerium oxide nanoparticles …

Hydrogels are three-dimensional cross-linked stable network insoluble in water, which gives
them a remarkable capacity to absorb both water and biological fluids. Hydrogel has been …

Developing articular cartilage substitutes required a combination of high compressive
strength, excellent biocompatibility and low friction. Despite great success in tough …

The hydrogel wound dressing is an ideal wound treatment because of its excellent
biocompatibility, high moisture resistance and the ability to activate immune cells to speed …

Hydrogels could be promising wound healing dressings that maintain a moist environment
in the wound site and accelerate wound healing. However, the lack of antibacterial effect …
