Chitosan |
3D polymer network, strong water absorption, excellent compatibility, non‐adhesive, degradable, and cost‐effective. |
For acute to chronic wounds, exudating, contaminated wounds, venous leg ulcers, diabetes, and first‐ and second‐degree burns. Have hemostatic and bacteriostatic action, and accelerate healing processes. |
[150] |
Collagen and gelatin |
Thermally and chemically stable with high tensile strength, permeable to O2, highly biocompatible, unable to retain, and expensive. |
Cover burn wounds and treat ulcers. Resistant to bacterial attack as well as further mechanical trauma. |
[151] |
Alginate |
Fibrous, highly absorbent, need a second dressing layer to avoid drying. |
Treat infected and noninfected wounds, and inappropriate for dry wounds. |
[152] |
Heparin |
Efficient binding with a variety of growth factors. |
Treat burns and diabetic foot ulcers. Participate in wound angiogenesis, cell growth, migration, and differentiation. |
[153] |
Cellulose |
3D network structure, high tensile strength, strong water holding capacity, permeability to gas and liquid. |
Used in scalds and ulceration. Facilitate autolytic debridement, improve the development of granulation tissue, and accelerate re‐epithelialization. |
[154] |
Hyaluronic acid |
ECM component, high water absorption and permeability, and fast degradation. |
Heal burns, epithelial surgical, and chronic wounds. Modulate wound via specific HA receptors, inflammation, cellular migration, and angiogenesis. |
