Bacterial nanocellulose, a natural, chemically pure biopolymer produced by microorganisms, is being well recognized as a highly biocompatible material. It has been already successfully applied as wet wound dressing and cosmetic facial mask, but its internal uses as artificial vessels, heart valves, and hernia meshes have been also conducted. Specific modifications of BNC make possible production of cartilage-like substitutes of meniscus, auricular, and nasal concha or even tubes for nerves regeneration. The final products are similar to natural tissues, with biocompatibility, moldability, biophysical, and chemical properties fitting the needs of regenerative medicine. Some of these biotechnological products have been already subjected to intensive in vivo investigation; some others, such as porous scaffolds for tissue engineering, are still under development. Recently, a lot of attention has been put into drug delivery systems production based on bio-cellulose. Continually, microbial cellulose offers a large field for systematic research on its new biomedical applications. |
