Chitosan and polyhexamethylene guanidine dual-functionalized cotton gauze as a versatile bandage for the management of chronic wounds

Antibacterial and antiviral chitosan oligosaccharide modified cellulosic fibers with durability against washing and long-acting activity

“…The cytotoxicity of chitosan oligosaccharide (COS), cellulose fibers, and modified fibers was evaluated by the CCK-8 assay on L929 cells [38] . The extract is obtained by soaking 10 mg of the samples (cellulose fibers and modified fibers) in a 10 mL phosphate buffer solution (PBS) for 24 h at 37 °C.…”

Silver loaded biodegradable carboxymethyl chitin films with long-lasting antibacterial activity for infected wound healing

“…A good wound dressing should have a suitable moisture level to maintain a suitable wet environment on the wound surface. 35,36 The water vapor permeance (WVP) values of the prepared carboxymethyl chitin films were determined (Fig. 1b).…”

Montmorillonite/Agarose Three-Dimensional Network Gel Sponge for Wound Healing with Hemostatic and Durable Antibacterial Properties

“…The wound-healing process proceeds in four phases: hemostasis, inflammation, proliferation, and remodeling . Among these, uncontrollable bleeding and bacterial infection are the main challenges in the early stages of wound healing. , To stop bleeding quickly and prevent infection, wounds are often treated clinically with hemostatic materials and antibiotic drugs. , Currently, there are many clinically available hemostatic materials, such as conventional wound dressing, , microporous aluminosilicates (zeolites and clays), , or various polymer-based materials (e.g., hydrogels, sponges, and films). − Although all of them have hemostatic functions, they still have some disadvantages. For example, conventional wound dressings are usually less effective and need long-term treatment .…”
