Abstract: Devices and methods for high-throughput manufacture of concentrically layered nanoscale and microscale fibers by electrospinning are disclosed. The devices include a hollow tube having a lengthwise slit through which a core material can flow, and can be configured to permit introduction of sheath material at multiple sites of Taylor cone formation formation.

Abstract: Systems and methods for electrospinning of core-sheath fibers are provided. The systems and methods achieve optimization of a shear stress that exists at a fluid boundary between core and sheath polymer solutions, by varying certain parameters of an electrospinning apparatus and/or the solutions used therewith.
