• , leading to superior functionality and enhanced metal sensing capabilities [111]. He et al. developed fluorescent fibers from alginate reinforced with gold (Au) nanoclusters by using a wet-spinning technique [112]. The fluorescent fibers exhibited good selectivity and sensitivity towards Cu2+ and Hg2

• were prepared by wet-spinning and coagulation in an ethanol bath. Thereby, no toxic components were introduced into the wet-spun chitosan fibers. After drying, the helical fibers had a diameter of approximately 130 µm. Scanning electron microscopy analysis of wet-spun helices revealed that the magnetic

• of nanometers to a few micrometers [21]. Blends of chitosan with alginate, silk, fibroin, cellulose or collagen can also be processed into composite fibers by electrospinning [22]. Wet-spinning is another well-established method of fabricating chitosan fibers with a diameter in the micrometer range

In this method SWCNTs are initially dispersed in an aqueous solution of poly(vinyl alcohol) (PVA) and are stabilized using surfactants. By applying the wet spinning method, a web of nanocomposite material fibers is produced where the
