A method for separating out a continuous single thread of fiber from many fiber branches and controlling alignment and deposition of said fiber on a substrate, comprising: electrospinning 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 fiber branch thread from the polymer fiber streams, wherein the single fiber branch thread is attracted to and intercepted by the collector shape, and depositing the single fiber branch thread as substantially aligned fiber on the collector.
