Chitin is the structural material of crustaceans, insects, and fungi, and is the second most
abundant biopolymer after cellulose on earth. Chitosan, a deacetylated derivative of chitin …

Hydrogels are versatile biomaterials characterized by three-dimensional, cross-linked,
highly hydrated polymeric networks. These polymers exhibit a great variety of biochemical …

Physically cross-linked hydrogels are used as scaffolds in tissue engineering applications
because they are easily produced and avoid the potential toxicity produced by chemical …

Chitosan is a unique biopolymer in the respect that it is abundant, cationic, low-toxic, non-
immunogenic and biodegradable. The relative occurrence of the two monomeric building …

Antioxidant and antimicrobial wound dressings are the most favorable for acute and chronic
wounds treatment. Herein, we formulated a multifunctional polyelectrolyte wound dressing …

Chitosan macro-and micro/nano-gels have gained increasing attention in recent years,
especially in the biomedical field, given the well-documented low toxicity, degradability, and …

Soft tissues are commonly fiber-reinforced hydrogel composite structures, distinguishable
