Nano - Robots: The Future is Tiny!
2008-08-19 | BBC
Marc Cieslak travels to Zurich in Switzerland to discover some of the ambitions scientists have for the world's tiniest technology. Far smaller than contemporary microtechnology, the developing field of nanotechnology deals with devices a thousand times smaller.
Microtechnology has already revolutionised the world by miniaturising the proportions of everything from mobile phones to laptops, and cramming more computing power into smaller devices.
Nanotechnology could lead to robots as small as blood cells and has already produced transistors at least a thousand times slimmer than a human hair.
This precision engineering involves manipulating molecules to exploit the unusual electrical and optical properties that operate at these small scales.
