What is electrospinning technology?
Electrospinning is a method to produce ultrafine (in nanometers) fibres by charging and ejecting a polymer melt or solution through a spinneret under a high-voltage electric field and to solidify or coagulate it to form a filament.
Who invented electrospinning?
The process of electrospinning was patented by J.F. Cooley in May 1900 and February 1902 and by W.J. Morton in July 1902. In 1914 John Zeleny, published work on the behavior of fluid droplets at the end of metal capillaries.
Why is electrospinning used?
Electrospinning has been utilized to generate nanofibers from various types of materials. The most commonly used materials are organic polymers in the form of either solution or melt. Small molecules can also be directly electrospun into nanofibers if they self-assemble and generate sufficient chain entanglement.
What is the purpose of electrospinning?
Electrospinning is a process used to fabricate continuous nanoscale fibers with diameters in the sub-micrometer to nanometer range using a high-voltage power supply.
Who invented nanofibers?
In 1900, American inventor John Francis Cooley (1861-1903) filed the first modern electrospinning patent. Anton Formhals was the first person to attempt nanofiber production between 1934 and 1944 and publish the first patent describing the experimental production of nanofibers.
What are the types of nanofibers?
Currently, there are three techniques available for the synthesis of nanofibers: electrospinning, self-assembly, and phase separation. Of these techniques, electrospinning is the most widely studied technique and has also demonstrated the most promising results in terms of tissue engineering applications.
Who is the father of tissue engineering?

How does electrospinning work?
The electrospinning technique is based on the application of a high electric potential between two electrodes of opposite polarities. This high voltage is able to overcome the surface tension inside a polymeric solution, or melt, allowing the complete evaporation of the solvent and the formation of fibrous structure.
Can electrospinning be used to mimic bone structure?
Electrospinning technique is recently being used to mimic the structure of bones by developing spiral structures intended for bone tissue engineering and reconstruction of bone defects [1,96–98]. Vaishali Bambole, Jatinder Vir Yakhmi, in Nanobiomaterials in Soft Tissue Engineering, 2016
Can electrospinning be used to develop tubular scaffolds for vascular tissue engineering?
The advances in nanotechnology ensure the capability of using electrospinning not only for developing scaffolds but also for creating tubular scaffolds for vascular tissue engineering. Yazdanpanah et al. [208] used electrospinning to fabricate nanofibrous scaffolds based on poly ( l -lactic acid) (PLLA) and gelatin [208].
What is needle-less electrospinning?
In needle-less electrospinning, the starting polymer solution is transferred to an open vessel where the fibers are generated from a stationary or rotating platform. Mass production of material is one benefit in the needle-less electrospinning process but there are many disadvantages.
