theweaselkingNanotech researchers have built tiny self-assembling machines that even grow their own muscles from cells taken from living animals.
Carlo Montemagno of the University of California and his team etched nanometer-scale lever arms into silicon chips then, without using chemicals that would kill cells, spanned the spaces from the lever arm's handle to an anchor point with a chrome/gold ribbon.
Finally, they added rat pup heart cells to the chips, which only stuck to the metal ribbon, and immersed it all in a sugary solution. The muscle cells divided and grew along the ribbon to create tiny muscles that can be stimulated to pull the levers.
"It's really a phenomenal thing," said George Bachand, a nanotech biologist at Sandia National Laborator
