Controllable Micro/nano Biofabrication of Fascinating Composites based on Bacterial Cellulose

Bacterial Cellulose-Based Biomimetic Composites

Multifunctional bacterial cellulose and nanoparticle-embedded composites

Cellulose, a linear polymer of glucopyranose sugar molecules, is synthesized both by plants and bacteria. The plant-produced cellulose is present along with other compounds such as hemicelluloses and lignin, and has been used historically for a wide variety of applications ranging from paper-making to cosmetics. The cellulose produced by bacteria, on the other hand, is pure and difficult to mak...

Preparation of Esterified Bacterial Cellulose for Improved Mechanical Properties and the Microstructure of Isotactic Polypropylene/Bacterial Cellulose Composites

Bacterial cellulose (BC) has great potential to be used as a new filler to reinforce isotactic polypropylene (iPP) due to its high crystallinity, biodegradability, and efficient mechanical properties. In this study, esterification was used to modify BC, which improved the surface compatibility of the iPP and BC. The results indicated that the cellulose octoate (CO) changed the surface propertie...

Synthesis and characterization of bacterial cellulose and gelatin-based hydrogel composites for drug-delivery systems

Bacterial cellulose and gelatin were successfully used to develop a hydrogel composite material. Hydrogel was synthesized by copolymerization between bacterial cellulose and gelatin. Scanning electron microscopy (SEM) images showed that the bacterial cellulose chain was uniform in size and shape. Glutaraldehyde was employed as a crosslinking agent. H-bonds were formed via the reaction between t...

Viability of human dermal fibroblasts cultured on bacterial cellulose and Aloe vera composites

Background Development of multifunctional scaffolds has allowed restructuration and improvement of native tissues, presenting characteristics that mimic complex tissues formation [1]. An ideal scaffold should provide enough transport of nutrients and also adequate mechanical support, allowing the incorporation of many cell types. Likewise, biocompatibility, mechanical properties and water reten...
