Nanofibers
Nanofibers
are fibers that are nanometers in diameter. Nanofibers can be derived from
different polymers and therefore have different physical properties and
potential for application. Different examples of natural polymers include
collagen, cellulose, silk fibroin, keratin, gelatin, and polysaccharides such
as chitosan and alginate. Polymer chains are connected by cooperative bonds.
The diameters of the nanofibers depend on the type of polymer used and the
method of production. All polymer nanofibers are unique for their large surface
area-to-volume ratio, high porosity, admirable mechanical strength, and
flexibility in operation compared to their microfiber parts.
Properties of nanofiber
1. Nanofibers can be
generated from different polymers.
2. It
has a diameters range of nanometers.
3. Polymer chains are
connected via covalent bonds.
4. Diameters of Nanofibers depend on the type of polymer used and the production method.
5. Nanofibers are
unique for their large surface area-to-volume ratio.
6. It has a high
porosity.
7. It has applicable
mechanical strength.
8. Good flexibility.
9. Nanofibers have many possible
technological and commercial applications.
Uses of Nano-fiber
1.
Nano-fiber is used in tissue engineering.
2. Nanofiber scaffolds are used in bone tissue engineering to
mimic the natural extracellular matrix of the bones.
3. Nano-fibers
are used as a possible drug carrier candidate. The
successful delivery of therapeutics to the intended target largely depends on
the choice of the drug carrier.
4. Surface-loaded
nanofiber scaffolds are useful as adhesion barriers between internal organs and
tissues post-surgery.
5.
Nano-fiber is used in cancer diagnosis.
6. It
is used in Lithium-air Battery making.
7. Quantum
dots show useful optical and electrical properties, including high optical gain
and photochemical stability. A variety
of quantum dots have
been successfully incorporated into polymer Nano-fibers.
