Temperature controlled electrospinning substrate

Abstract

A device having: an article having a flat surface and a lower surface opposed to the flat surface; a cavity formed in the lower surface forming a complete loop surrounding a central portion of the article; a heating element having the same shape as the complete loop in the cavity and positioned to warm a portion of the flat surface adjacent to the heating element when the heating element is activated; a cooling device positioned to cool a portion of the flat surface in the central portion; and a release layer on the flat surface. A device having: an article having an upper surface; a heating element on the upper surface forming a complete loop surrounding a central portion of the article; and an electrically insulating material on the upper surface within the central portion.
