Nanofibers are lighter material with higher surface areain comparison to polymeric film. The ease of producingfunctional nanofiber is another advantage over many nano-materials. Functional nanofiber in particular has attained agreater interest in recent years.The applications of functionalnanofibers are increasing in various technical fields such aswater filter membranes, tissue engineering, biosensors, drugdelivery systems, wound dressings, catalysis, antibacterial.This special issue is comprised of well-selective articles thatdiscuss production of functional nanofibers their applicationsin different emerging fields.
M. Zhang et al. have presented exciting work on drugdelivery using nanofibers. They used collagen that wasextracted from abandoned Rana chensinensis skin in north-eastern China via an acid enzymatic extractionmethod.Theydemonstrated two different nanofiber-vancomycin (VCM)systems, that is, VCM blended nanofibers and core-shellnanofibers with VCM in the core, and both systems sustainedcontrol release for a period of 80 hours. Another workwas presented by R. Takai et al. on blood purificationusing composite nanofibers. About 10% of the populationworldwide is affected by chronic kidney disease (CKD). Theauthors developed nanofiber meshes zeolite-polymer com-posite nanofibers for efficient adsorption of creatinine, whichis a simpler and more accessible method for hemodialysis(HD) patients.
The authors from Brazil M. Martelli-Tosi et al. tookthe advantage of abounded raw material soya bean andproduced cellulose nanofibers from soybean straw.They used
a commercial enzyme to extract nanofibers. This enzymatic-mechanical treatment yields cellulose nanofibers with diam-eters of 5–15 nm that can be useful for biotechnologicalapplications such as generation of bioethanol or biogas.Besides many other techniques, C. K. Saurabh et al. iso-lated cellulose nanofibers (diameter, 5–10 nm) from Gigan-tochloa scortechinii bamboo fibers. The resultant cellulosenanofibers were used as reinforcement material in epoxybased nanocomposites and showed improvement in tensilestrength, flexural strength, and modulus of nanocomposites.N. H. Mohd et al. discussed modification on nanocrystallinecellulose properties derived from empty fruit bunches andshowed the potential application for CO
2capture.
B. Yalcinkaya et al. reported thin-film nanofibrous com-posite membrane for dead-end seawater desalination fornanofiltration. The composite membrane consists of a three-layer system including a nonwoven part as the support-ing material, a nanofibrous scaffold as the porous surface,and an active layer.

Carbon nanomaterials such as carbon nanotubes, carbonnanofibers, and graphene have recently been explored forenergy storage application such as supercapacitor due toadditional high specific surface area and unique electrical andchemical inertness properties. A. M. Saleem et al. presenteda comprehensive review on performance enhancement ofcarbon nanomaterials for supercapacitors. C. H. Su and C.H. Huang discuss the impact of substrate outgassing on thegrowth of carbon nanotubes (CNT) using the single-pulsedischarge method with aim to develop a simpler, safer, andmore energy efficient technique for growing CNTs havingzonal selectivity.
In summary, all authors put their great effort to presentthe production of functional nanofibers and showed varietyof applications in different technical fields. We hope thisspecial issue will provide better understanding of the subjectand also provide new horizon of functional nanofibers.
