During the last two decades there has been tremendous interest in the advancement of electrospun nanofibers. These 1D nanomaterials show great promise in the development of new products applicable in various fields such as biomedicine, catalysis, energy, the environment, sensing, etc. This is attributed to their unique properties (including their extremely long length, high surface-to-volume ratio, ease of functionalization and versatility in chemical composition), the possibility of generating nanofibers exhibiting specific orientation, porosity, and topography, their tunability in terms of fiber morphology (core–shell, hollow, helical, necklace-like, etc.) and most importantly the high potential for their mass production. Furthermore, the...
