These unique characteristics plus the functionalities
from the materials themselves impart nanofibers with a number of novel properties for
applications in areas as various as biomedical engineering, wound healing, drug
delivery and release control, catalyst and enzyme carriers, filtration, environment
protection, composite reinforcement, sensors, optics, energy harvest and storage, and
many others. More and more emphasis has recently been placed on large-scale
nanofiber production, the key technology to the wide usages of nanofibers in practice....
