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 Ag nanoparticles containing bacterial cellulose nanoflbers exhibited strong antimicrobial activity, indicating wound-dressing applications [25]. Gelatin fiber mats with antibacterial activity against some common bacteria found on bum...

Bacterial cellulose has a wide range of potential biomedical applications such as tissue engineered cartilage scaffolds [142, 143] wound dressing [144—148]... 

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).

Microbial synthesis of ceUulosic fibres affords the opportunity of obtaining products with unique properties suitable for practical application in medicine and the electronics industry. For synthesis of modified bacterial cellulose, the Acetobacter subsp. strains have been applied. The selection of suitable polyaminosaccharide modifiers allows the production of bacterial cellulose characterised by valuable mechanical, electro-acoustic and biological properties. Practical applications of this ceUulosic composite material for manufacture of novel wound-heaUng dressings as well as diaphragms for loudspeakers have been tested. ... 

The chitosan-modified bacterial cellulose, characterised by unique properties, i.e. bioactivity, biodegradability, biocompatibility, no toxicity and non-allergic action, coimected with good mechanical tenacity, has been found to be a great material for biomedical applications such as dressings for wound healing. ...

Cellulose microfibrils were initially proposed to have potential in various biomedical applications, like drug carriers and topical wound dressings [22, 86). Membranes based on bacterial cellulose microfibrils have been successfully used as wound-... 

Specialty absorptive and composite dressings are composed of various combinations of foams, gels and absorbent fibers such as cellulose, cotton or rayon. They may be laminates with or without an adhesive border, and may be covered with a moisture permeable, bacterial barrier. Constructions are designed for management of wound fluid level and enhanced ease of use.
