See this image? It could be printed on a human hair.
The highest possible resolution images — about 100,000 dots per inch — have been achieved, and in full-colour, with a printing method that uses tiny pillars a few tens of nanometres tall. The method, described today in Nature Nanotechnology1, could be used to print tiny watermarks or secret messages for security purposes, and to make high-density data-storage discs.
