In this study, a novel scaffold was fabricated from nematically ordered polysaccharide molecules such as cellulose, chitin and cellulose-chitin blend (50–50%), termed as NOC, NOCh, NOC-Ch, by deposition of biotic nanofibers such as bacterial cellulose (BC) and collagen, which were prepared by aqueous counter collision method to allow the fiber width to reduce into nano-scales by high pressure impinging...
The aqueous counter collision (ACC) method can provide single bacterial nanocellulose ribbons (ACC-BNC) in a desired width, from a pellicle produced by Gluconacetobacter xylinus. Kose et al. (Biomacromolecules, 12:716–720, 2011) reported that the ACC process transformed the major Iα crystalline phase of the native fiber to a stable Iβ phase, without decreasing the overall crystallinity. The current...
This study involved a detailed investigation of a novel approach to reducing naturally occurring cellulose fibers into nanofibers solely by the use of aqueous counter collision (ACC) without any chemical modification. In this process, equivalent aqueous suspensions of cellulose are ejected from dual nozzles and collide at high speed and pressure. Even a few repetitions of the collision process are...
