Wound dressing cellulose

Because of the extraordinary supramolecular structure and exceptional product characteristics as high-molecular and high-crystalline cellulosics with a water content up to 99%, nanocelluloses require increasing attention. This review assembles the current knowledge in research, development, and application in the field of nanocelluloses through examples. The topics combine selected results on nanocelluloses from bacteria and wood as well as their use as technical membranes and composites with the first longtime study of cellulosics in the animal body for the development of medical devices such as artificial blood vessels, and the application of bacterial nanocellulose as animal wound dressings and cosmetic tissues.

The modification of polymers and fibrous surfaces to alter the porosity, wettability and other characteristics of polymeric substrates, will enable the prodnction of implants and biomedical devices which exhibit greater resistance to microbial adhesion and biofilm formation. A nnmber of polymers have been developed that can be incorporated into cellulose and other materials, which will provide significant advances in many fields snch as food packaging, textiles, wound dressings, coating of catheter tnbes and sterile surfaces.

Bacterial Cellulose has been shown to be a highly effective wound dressing material. In fact, the results of burns, diabetic ulcer, healing process can be show in Figs. 10.5 and 10.6a,b. The biomedical applications of BC include meniscus replacements (pig meniscus on the left, BC meniscus on the right), artificial blood vessels and wound dressing for skin healing [12, 20, 21] (Fig. 10.7).

For more than 5000 years, cellulose fabrics and fibers have been used in medicine as wound dressings for treatment of wounds and burns. In the twentieth century, along with cellulose dressings, various cellulose derivatives, powdered and microcrystalline cellulose began to be used, and in the twenty-first century nanocellulose joined these products. Among various organic substances, cellulose is the most appropriate for preparation of nanoscale materials, since this most abundant natural polymer has nanostmctured organization, which promotes isolation of free nanoconstituents.
