    摘要: The present invention relates to compositions and method for drawing egel silk fibroin fibers. The resulting fibers can transmit light and hence can be used as optical fiber. Silk fibroin fiber is produced by a method comprising applying an electric field to a solubilized silk fibroin solution to create a silk fibroin gel; converting the silk fibroin gel to a viscous silk liquid; and drawing a silk fiber from the viscous silk liquid. The silk fiber of the invention can be used in materials such as textile, medical sutures, and tissue materials, as well as conferring optical properties into these materials.

    摘要: The present invention relates generally to methods to produce various desired patterns (e.g., coils) via an electrospinning process where such desired patterns possess certain desired properties (e.g., desired electrical properties). In one embodiment, the present invention relates to a method for producing coiled fiber patterns at a rate of one turn of the coil in a set time period (e.g., about one microsecond). In another embodiment, the present invention relates to methods to produce “resonator structures” that are the basic element of artificial dielectrics. In still another embodiment, the present invention relates to methods to produce coils with various specified diameters (e.g., about 10 microns) which can, among other things, enable the production of repeating patterns in a wallpaper-like array. In still yet another embodiment, the present invention relates to methods to hierarchical structures that offer mechanical support for various nanofibers.
