Abstract
Exemplary embodiments provide systems, devices and methods for the fabrication of three-dimensional polymeric fibers having micron, submicron and nanometer dimensions, as well as methods of use of the polymeric fibers.
Claims13
A device for formation of one or more micron, submicron or nanometer dimension polymeric fibers, the device comprising:
- a reservoir for holding a polymer and including a lateral surface having one or more orifices for ejecting the polymer for fiber formation;
- a motion generator configured to impart rotational motion about an axis of rotation to the reservoir, the rotational motion of the reservoir causing ejection of the polymer radially outward with respect to the axis of rotation from the one or more orifices;
- and
- a collection device configured to hold a liquid, and the collection device configured and positioned to accept the polymer ejected from the reservoir;
- wherein the reservoir and the collection device are positioned and configured such that the one or more orifices of the reservoir are submerged in a liquid held in the collection device during rotational motion of the reservoir;
- and
- wherein the device is configured such that the ejection of the polymer into the liquid in the collection device causes formation of one or more micron, submicron or nanometer dimension polymeric fibers.
