This image created by IBM scientists demonstrates a new nano "printing" technique they believe will lead to breakthroughs in ultra-tiny chips, optics, and biosensors. The recreation of Robert Fludd's 17th century drawing of the Sun – the alchemists’ symbol for gold -- was created by precisely placing 20,000 gold particles, each about 60 nanometers in diameter. This method could be used for mass production to place particles as small as 2 nanometers in diameter to fabricate atomic scale nanowires, ultra tiny lenses for optics and biosensors for healthcare.
