Method and device for protein fiber production
A method for producing a protein polymer fiber, the method comprising providing a liquid protein solution in a container for liquid, and repeatedly moving the liquid surface in the container back and forth between a first and a second position. Said movement of the liquid surface is such that the protein polymer solution is allowed to form a film in the interface between the liquid surface of the liquid protein solution and a surrounding fluid. The movement of the liquid surface being performed by respectively raising and lowering the liquid surface relative to the container or by moving an object extending through the liquid surface of the liquid protein solution. Also, a device for performing said method.

Methods for the fabrication of polymeric fibers
In accordance with an exemplary embodiment, a method is provided for forming a micron, submicron and/or nanometer dimension polymeric fiber. The method includes providing a stationary deposit of a polymer. The method also includes contacting a surface of the polymer to impart sufficient force in order to decouple a portion of the polymer from the contact and to fling the portion of the polymer away from the contact and from the deposit of the polymer, thereby forming a micron, submicron and/or nanometer dimension polymeric fiber.
