Nanofibers, mainly fabricated by electrospinning, are considered as one of the safest nanomaterials due to their extremely long length and their ability to be embedded within other media. Recent advancement in mass production of nanofiber has made it practical to use nanofibers in many emerging fields. In order to enhance the nanofiber capability to use in a particular application, functional nanofibers always serve as a better candidate. The prominent and potential applications of functional nanofibres are in filter media, biosensors, wound dressings, controlled drug release, tissue engineering scaffolds, smart protective clothing, energy, and environment and many other emerging fields.
