IBM Prints Tiniest Image In Gold 'Ink'

Researchers at IBM and ETH Zurich (an international research organization) have demonstrated a new, advanced way to "print" REALLY SMALL IMAGES with unprecidented accuracy and resolution. The technique enables printing with 60-nanometer "dots" (100 times smaller than a human red blood cell) at a resolution of 100,000 dots per inch. The researchers showed off by printing this image of Robert Fludd’s 17th-century image of the sun (the alchemists’ symbol for gold). The image is made, according to a press release, with "roughly 20,000 gold particles, each of them 60 nanometers in diameter. The printing method precisely placed one particle per dot, thus creating the smallest piece of artwork ever printed from single pigment particles."
