Nanofibers based on poly(vinyl alcohol) as the matrix, and nanocrystals of a-chitin (ca. 31 nm in width and ca. 549 nm in length) as the nanofiller were prepared by Junkasem et al. [51]. The average diameters of the electrospun fibers ranged between 175 and 218 nm. The addition of increasing amounts of the whiskers caused the crystallinity of poly(vinyl alcohol) within the nanocomposite materials to decrease and the glass transition temperature to increase.

Nanofibrillar chitin hydrogels are biodegradable, biocompatible, and nontoxic, and thus show promise for biomedical applications. The protonation of amino groups on the surface of chitin allows its application in wound dressings due to the antimicrobial properties of cationic gels [130]. Polymeric fibers that mimic the structure and function of the extracellular matrix are also of interest in tissue engineering and cell culture. Chitin nanofibers can promote cell attachment and show potential as extracellular matrix mimics [29, 125].

Potential applications of scaffolds made from chitosan and chitin nanofibers have been explored in tissue engineering. Chitin and chitosan can be electrospun into nanoscaffolds that could resemble the native extracellular matrix and have improved cytocompatibility for tissue engineering...
