Tissue engineering scaffolds
fabricated from nanofibers are gaining importance due to their unique
similarity to extracellular matrices, high porosity, and ease of
fabrication. Also the nanofibers have an advantage of enormous surface
area due to very high length to diameter ratio of the fibers. A very
elegant process to make the nanofiber scaffolds is by subjecting the
polymer solution or melts to very high potential difference. A variety
of parameters such concentration, melt viscosity, potential difference
etc. can be optimized to obtain desired diameter and morphology of the
resultant nanofibers. Further these nanofibers can also be formed to
three dimensional scaffolds that can be used as the scaffold for tissue
engineering.
In
our laboratory, we are investigating the different ways to fabricate two
and three dimensional nanofibers from a variety of biodegradable and non
biodegradable polymers that could be used for a various biomedical
applications.
