Bacterial cellulose (BC), cellulosic nanofibers produced by bacteria, has extraordinary potential as functional bio-composite materials. It has a nano scale three-dimensional network structure and micro scale which binds together by inter-and intra-fibril hydrogen bonds. For this unique structure, BC shows a superior properties such as high crystallinity, fine network, high water holding capacity, large surface area, elasticity, high mechanical strength, porosity and thermal stability. Such properties make BC a promising material for biocomposite materials. Recently, it is used in many biomedical and biotechnological application, such as tissue engineering, drug delivery, wound dressings, and medical implants. In this Presentation, several basic properties of BCs will be discussed to be used for cell encapsulation. |
