The diameters of nanofibers depend on the type of polymer used and the method of production. [5] All polymer nanofibers are unique for their large surface area-to-volume ratio, high porosity, appreciable mechanical strength, and flexibility in functionalization compared to their microfiber counterparts.

Researchers are using nanofibers to deliver therapeutic drugs. They have developed an elastic material that is embedded with needle like carbon nanofibers. The material is intended to be used as balloons which are inserted next diseased tissue, and then inflated.
A nanofiber has two external dimensions in the nanoscale, with nanotubes being hollow nanofibers and nanorods being solid nanofibers. A nanoplate/nanosheet has one external dimension in the nanoscale, [ 20 ] and if the two larger dimensions are significantly different it is called a nanoribbon .
Nanocellulose is a term referring to a family of cellulosic materials that have at least one of their dimensions in the nanoscale.Examples of nanocellulosic materials are microfibrilated cellulose, cellulose nanofibers or cellulose nanocrystals.
The use of nanofiber webs as a filtering medium is well established. Due to the small size of the fibers London-Van Der Waals forces are an important method of adhesion between the fibers and the captured materials. Polymeric nanofibers have been used in air filtration applications for more than seven decades.
[1] [2] These nanofibers have been shown to detect various gaseous chemicals, such as hydrogen chloride (HCl), ammonia (NH 3), Hydrazine (N 2 H 4), chloroform (CHCl 3), and methanol (CH 3 OH). [1] PANI nanofibers can be further fined-tuned by doping and modifying the polymer chain conformation, among other methods, to increase selectivity to ...
Nanofibers are key to the story and outcome of '3 Body Problem,' Netflix's major new sci-fi series. ... —Auggie's nanofiber technology is essentially used as an invisible, razor-sharp lattice ...
Researchers from Rice University and State University of New York – Stony Brook have shown that the addition of low weight % of carbon nanotubes can lead to significant improvements in the mechanical properties of biodegradable polymeric nanocomposites for applications in tissue engineering including bone, [6] [7] [8] cartilage, [9] muscle [10] and nerve tissue.
