nanofiber is one of the major successes of nanotechnology

For those who are unfamiliar, Nanotechnology has provided several novel products with superior properties for a wide range of applications and nanofiber is one of the major successes of nanotechnology.
For instance, nanofibers are being used to improve air filtration efficiency of filters and media in pharmaceutical industries.
Nanofiber webs act as protective fabrics against infectious and environmental agents in the pharmaceutical industry in addition to providing affinity membranes for filtering heavy metals, which was difficult by conventional purification methods.
