Fabrication of CNT micro-cloths using electrode needles. (a) A schematic cofiguration of the electrode needles. These electrode needles are inserted into a suspension of DNA-CNT mixture, collecting aligned CNTs between them. (b, c) Digital microscope images of a dried CNT film with its edge attached to one of the electrode needles (b) and another sheet placed on a substrate after separation from the electrode pair (c). Scale bars: 50 μm.
