Bacterial NanoCellulose (BNC) is a biocompatible biopolymer that occurs naturally from a variety of strains and has received great attention in biomedical applications due to its various beneficial properties.
When properly purified, Bacterial NanoCellulose (BNC) hydrogels are pure, containing only nanocellulose fibers organized in collagen-like structures, and contain no endotoxins, making them safe to use and study in humans, despite being of origin. bacterial.
Due to its large surface area,Bacterial NanoCellulose (BNC) also presents many opportunities for high liquid retention, porosity, compatibility and functionality. For these reasons, much attention has been paid to the use of Bacterial NanoCellulose (BNC) as a drug delivery or depot system.
In addition, Bacterial NanoCellulose (BNC) is stable for a long time at room temperature, can be made from various carbon sources (sugar), can be adjusted in size, shape and thickness, and is easy to sterilize, so it can be easily manufactured. and economic. .
Finally, their non-animal origin can reduce the risk of disease transmission, ethical concerns, and reliance on donated tissue.
All these unique properties make Bacterial NanoCellulose (BNC) a very interesting and suitable biomaterial for wound healing. In fact, Bacterial NanoCellulose (BNC) is already used in cosmetic masks and skin tissue regeneration. In addition, internal applications such as artificial blood vessels, heart valves, cartilage, and hernia mesh are currently being studied. However, its ability to heal other body surfaces, such as the cornea, remains largely unexplored.
For this reason, it is currently being investigated whether Bacterial NanoCellulose (BNC) is suitable as an ocular drug delivery system and as a new corneal dressing that promotes wound healing.
