“…Nonetheless, the potential of such fibers beyond simple light transmission is already envisioned since they have demonstrated the potential for use in drug delivery and sensory applications, controlled degradation, and feasibly modifiable functional fiber optic nanocomposites [ 36 , 118 , 125 ]. On the other hand, a range of cellulosic components have been frequently coupled with traditional optical fibers and into photonic devices to utilize, for instance, their sensitivity to humidity or the structural colors and chirality of liquid crystalline CNCs which broaden the application potential and cooperation with traditional light transmission methods [ 13 , 126 , 127 , 128 ]. Overall, work still remains, especially in finding and optimizing the best cellulose derivatives for optical fiber preparation for different purposes and standardizing such fibers’ quality and processing conditions before any larger scale production becomes topical.…”

Chemical modification of cellulose offers routes for structurally and functionally diverse biopolymer derivatives for numerous industrial applications. Among cellulose derivatives, cellulose ethers have found extensive use, such as emulsifiers, in food industries and biotechnology. Methylcellulose, one of the simplest cellulose derivatives, has been utilized for biomedical, construction materials and cell culture applications. Its improved water solubility, thermoresponsive gelation, and the ability to act as a matrix for various dopants also offer routes for cellulose-based functional materials. There has been a renewed interest in understanding the structural, mechanical, and optical properties of methylcellulose and its composites. This review focuses on the recent development in optically and mechanically tunable hydrogels derived from methylcellulose and methylcellulose–cellulose nanocrystal composites. We further discuss the application of the gels for preparing highly ductile and strong fibers. Finally, the emerging application of methylcellulose-based fibers as optical fibers and their application potentials are discussed.

“…[78,117] Calcium alginate hydrogel, hydroxypropyl methylcellulose hydrogel, and polyvinyl alcohol (PVA) hydrogel can be used as humidity sensitive materials for optical fiber humidity sensors. [118][119][120][121] On the other hand, they can be used as matrix to encapsulate or immobilize specific chemicals, luminescent materials or biological receptors for biochemical detection. For example, the PVA/PAA hydrogel film chemically modified by 8-hydroxyquinoline (8HQ) is sensitive to Ni 2+ and can be used for the detection of Ni 2+ concentration in aqueous solution.…”

Optofluidic, as an emerging technology that combines photons and microfluidics, has become a powerful, intelligent, and universal sensing platform in the field of bio-chemical sensing. Optical fiber optofluidic (OFOF), as a branch of optofluidic technology, has stimulated a host of remarkable achievements in the field of bio-chemical sensing due to its superiority of compact structure, immunity to electromagnetic interference, low sample consumption, high sensitivity, and real-time dynamic response. In this paper, an overview of OFOF bio-chemical sensors is presented. The OFOF system architectures are introduced and some advanced functional materials and coating technologies that can be utilized in the OFOF sensing platform to achieve high-performance biochemical sensing are summarized. Research progress and current status of OFOF bio-chemical sensors based on various sensing mechanisms are summarized and analyzed, with emphases on their sensing principles, sensing structures, sensing applications, advantages, and disadvantages. Lastly, the existing challenges and future development trends of OFOF biochemical sensors are briefly discussed.
