Bacterial cellulose composite materials

altBacterial cellulose is produced by some fungi and bacteria. It is an attractive material with increasing number of uses and is becoming a potential material platform to create novel complex hybrid nanocomposites. Bacterial cellulose, contrarily to plant cellulose, does not contain traces of lignin, hemicellulose or pectin, and has higher crystallinity, water holding capacity and mechanical properties. Moreover, once dried, it forms a resistant, ultrafine, porous and flexible membrane. All these properties, and the fact that it can be easily functionalized with organic or inorganic molecules or nanoparticles, and shaped in 2D or 3D shapes, offers the possibility to a wide range of applications in many different fields, such as optics, electronics, medical, food industry or even photonics. Some of the publications related to bacterial cellulose in our group are the following:
