Use of Electrospinning to Directly Fabricate Hollow Nanofibers with Functionalized Inner and Outer Surfaces

Within or without: With the use of a coaxial, dual-capillary spinneret, electrospinning has been demonstrated as a versatile tool to fabricate hollow nanofibers with either their outer or inner surfaces being functionalized by molecular species or nanoparticles (the pictures show schematic cross sections of the functionalized hollow nanofibers).
