Abstract
A method for separating out nano-scale fiber threads from many fiber branches and controlling alignment and deposition of the fiber threads on a substrate, comprising: electrospinning at least synthetic polymer fiber streams from an electrically charged syringe needle; controlling the fiber using at least one electrically charged metallic disk rotating about an axis positioned below the needle; capturing the fiber using electrically grounded collector; extracting a single or plurality of fiber branch threads from the fiber streams, wherein the single or plurality of fiber branch threads is attracted to and intercepted by the collector shape, and depositing the single or plurality of fiber branch threads as substantially aligned fiber on the collector.
