Nanofiber structures (IMAGE) National Institutes of Natural Sciences Caption Structure of double-helix supramolecular nanofibers assembled from 'bitten' warped nanographenes (bWNG). (Upper left) An assembly of two bWNGs. (Lower left) Top view of a nanofiber. A double-helix with a diameter of 2.8 nm is formed with each molecule shifted by 45 degrees. (Middle) Side view of a nanofiber. (Right) Nanofiber bundles.
