Pull Spinning Novel Technique
for Production of Nanofibers

Very thin fibers are of great value as the building block for creating materials, analogous to the weaving of cloth from threads. Fibers formed of biopolymers or proteins would provide the components from which to create biocompatible structures on which cell could grow. Parker's team developed a new method for creating such fibers: Pull Spinning. It is a unidirectional nanofiber fabrication technique that exploits a balance between adhesion, inertial, gravitational, and centrifugal forces to pull and elongate a drop bearing the biopolymer into a solid nanofiber.
