Carboxymethyl chitosan is an important water-soluble chitosan derivative with many medical effects, such as promoting wound healing, hemostasis, scar inhibition, analgesia and antibacterial effects. It is also widely used in chemical industry, environmental protection and health care products. [2-6] Carboxymethyl chitosan has good biocompatibility and biodegradability. It is widely used in hydrogels and wound healing biomaterials, and is also widely used in tissue engineering matrix materials. In addition, carboxymethyl chitosan can be easily processed into nanoparticles, making it more suitable for drug delivery, bioimaging, biosensors and gene therapy. In recent years, carboxymethyl chitosan has also been widely used in green chemistry. Due to its unique biological properties, carboxymethyl chitosan has a wide range of applications in biomedicine and pharmaceutical fields.

Promote wound healing
Carboxymethyl chitosan can promote the growth of fibroblasts and epidermal keratinocytes, and can effectively accelerate the wound repair process.
Inhibit scar hyperplasia
Carboxymethyl chitosan can significantly promote the proliferation of normal skin fibroblasts, but inhibit the proliferation of keloid fibroblasts.
Analgesic effect
Apply 3% carboxymethyl chitosan saline solution to the burn wound, and the concentrations of pain-causing factors bradykinin and 5-hydroxytryptamine in the blood are detected by enzyme-linked immunosorbent assay, and both are significantly reduced. These results show that carboxymethyl chitosan has a significant analgesic effect.
Hemostatic effect
Carboxymethyl chitosan can quickly stop bleeding, and the hemostatic mechanism does not depend on low molecular weight heparin.
Antibacterial and anti-infection
The non-woven fabric made of carboxymethyl chitosan and acetic acid has excellent air permeability and water permeability. It is used for large-area burns and scalds, and has good anti-infection and wound healing effects.
Anti-tumor
Hypoglycemic effect
Carboxymethyl chitosan water-soluble powder has a significant effect on lowering blood sugar, pancreatic islet cell proliferation.
