Nanofibers have a range of applications in medicine, cosmetics, environmental monitoring, energy generation and the manufacture of smart materials. The high surface area-to-volume ratio of these nanomaterials is highly beneficial for drug delivery and catalysis, and their controllable pore sizes, that can be tailored to selectively exclude components like bacteria or pollutants, makes nanofiber webs ideal for filtration, tissue engineering and wound care. Nanofibers are also versatile in that additives can be encapsulated within the fibers or coated on to the surface. The choice of the polymer and the nanofiber dimensions can be changed to obtain specific material properties.
