New, Invisible Nano-Fibers Conduct Electricity, Repel Dirt -- 1 (IMAGE) Ohio State University Caption A drop of water balances perfectly on a plastic surface invented by researchers at Ohio State University. The surface is covered with microscopic fibers, and can be made to attract or repel water. The surface shown here is water repellant, so the drop can't spread out along the surface; instead, it retains its spherical shape. Credit Photo by Jo McCulty, courtesy of Ohio State University.
