Methods of making three dimensional structures having aligned nanofibers and the resulting structures produced by such methods

Abstract

Apparatus for producing a three dimensional nanofiber structure includes (1) at least two spaced electrodes; (2) a spinner adapted to rotate the at least two spaced electrodes; (3) a syringe assembly adapted to eject a polymer solution from a syringe of the syringe assembly towards the at least two spaced electrodes while the at least two spaced electrodes are rotated by the spinner; and (4) a power supply assembly for providing the two spaced electrodes at a first electric potential, and for providing the syringe at a second electric potential which is different from the first electric potential. A composition of matter may include (1) a least one layer of nanofibers in which a distribution of angles of fibers is “aligned;” and (2) at least one gel layer, wherein the at least one layer of microfibers and the at least one gel layer alternate to form a laminate.
