Fig. 2 Scaffold architecture affects cell binding and spreading. The examples were obtained by (a) phase separation/leaching combination and (b-d) electrospinning. Porosity data was roughly estimated note that classic nanofiber structure is <100 nm, but here is <1000 nm, as found commonly in biomedicine. Scale bars (a) 500 pm, (b-d) 10 pm.

Electrospinning techniques enable the production of continuous fibers with dimensions on the scale of nanometers from a wide range of natural and synthetic polymers [135]. The number of recent studies regarding electrospun polysaccharides and their derivatives, which are potentially useful for regenerative medicine, is dramatically increasing. 

This chapter is devoted to a discussion of the fabrication of nanofibres as a biomaterial and the use of them as such. Several approaches to this fabrication have been included, focusing on the extraction of nanofibrils from natural materials by both mechanical and chemical means and electrospinning from a wide range of materials (both natural and synthetic). Of these, electrospinning has received greater attention for a number of reasons it is convenient to operate, its processing parameters can be well controlled and it is the most likely to reach the scale of mass, industrial production. 

FIGURE 5.26 Schematic of electrospinning of PEO nanofiber templates containing FeCh followed by vapor phase polymerization of pyrrole. An SEM image of the resulting PPy-PEO composite nanofibers is shown at top right comer. The scale bar for the image is about 500 nm. (After Nair, S., Natarajan, S., and Kim, S. H. 2005. Macromol.
