“…Additionally large surface area for immobilization of the analytes, rapid response, high sensitivity, good reproducibility and anti-interference are also required characteristics. As expected, it is a great challenge to develop a single material that include all these important characteristics [63]. Cellulose based sensors are inexpensive, disposable, and environmentally friendly.…”

“…These materials transport liquids via capillary action with no need of external power [88]. BC/Au nanocomposites have been reported to exhibit good sensitivity, low detection limit and fast response toward hydrogen peroxide makingthese materials suitable matrices for enzyme immobilization [61][62][63]. The practical application of these nanocomposites for glucose biosensors in human blood samples has been reported.…”

“…Thermally stable proton-conducting membranes have been prepared by the in situ deposition of Pt NPs on BC membranes, via liquid phase chemical deoxidization method in the presence of the reducing agents NaBH 4 or HCHO [65]. The obtained black nanocomposite have been reported to display high electrocatalytic activity, with good prospects to be explored as membranes in fuel cell field [63]. However in case of Pt/cellulose nanocomposites, the reducing groups of cellulose are less effective in the reduction of metal precursors.…”

Research on inorganic/organic nanocomposite materials is a fast growing interdisciplinary area in materials science and engineering. In particular, extensive work has been undertaken in the development of sustainable and environmentally friendly resources and methods. A key idea has been the production of nanocomposites comprising biopolymers that in specific contexts can replace conventional materials such as synthetic polymers. It is well known that the properties of nanocomposite materials depend not only on the properties of their individual components but also on morphological and interfacial characteristics arising from the combination of distinct materials [1]. Therefore the use of polymers such as cellulose, starch, alginate, dextran, carrageenan, and chitosan among others, gain great relevance not only due to their renewable nature and biodegradability, but also because a variety of formulations can be exploited depending on the envisaged functionality [2, 3]. This chapter has focus on the use of cellulose as the matrix in the production of nanocomposites. Cellulose has critical importance namely because is the most abundant and widespread biopolymer on Earth. Owing to its abundance and specific properties, it is important noted for the development of environmental friendly, biocompatible, and functional composites, quite apart from its traditional and massive use in papermaking and cotton textiles [4]. Additionally different types of cellulose are available for the preparation of nanocomposites, namely vegetable cellulose (VC), bacterial cellulose (BC) and nanofibrillated cellulose (NFC). Although sharing similar chemistry and molecular structure, the different kinds of cellulose show important differences in terms of morphology and mechanical behavior. For example, BC and NFC are composed of fibers with nanosized dimensions as compared to VC, which might impart new properties, and in some cases improvements to the ensuing nanocomposite materials [5].

“…This strategy is not limited to a particular detective material or gases, but can be widely used with different detective materials and for detecting different gases. BC composites with gold nanoparticles (BC‐Au) have been used for enzyme immobilization and glucose biosensor fabrication [56, 81]. A biosensor composed of horseradish peroxidase (HRP)/Au‐BC nanocomposite displayed outstanding results, including a wider linear range, narrow detection limits, and quick response toward hydrogen peroxide, suggesting that Au‐BC nanocomposite could be a suitable matrix for enzyme immobilization [81].…”

Bacterial cellulose (BC), owing to its pure nature and impressive physicochemical properties, including high mechanical strength, crystallinity, porous fibrous structure, and liquid absorbing capabilities, has emerged as an advanced biomaterial. To match the market demand and economic values, BC has been produced through a number of synthetic routes, leading to slightly different structural features and physical appearance. Chemical nature, porous geometry, and 3D fibrous structure of BC make it an ideal material for composites synthesis that successfully overcome certain deficiencies of pure BC. In this review, we have focused various strategies developed for synthesizing BC and BC composites. Reinforcement materials including nanoparticles and polymers have enhanced the antimicrobial, conducting, magnetic, biocompatible, and mechanical properties of BC. Both pure BC and its composites have shown impressive applications in medical fields and in the development of optoelectronic devices. Herein, we have given a special attention to discuss its applications in the medical and electronic fields. In conclusion, BC and BC composites have realistic potential to be used in future development of medical devices, artificial organs and electronic and conducting materials. The contents discussed herein will provide an eye-catching theme to the researchers concerned with practical applications of BC and BC composites.
