Miniaturization to the Max: Nanotech Pioneer Lauded

Machines, medicines, and materials a mere fraction the width of a human hair may one day store trillions of bits of information, detect the onset of cancer, and restore a paralyzed limb.

But before the promise of nanotechnology is even modestly met, scientists must first learn how to make three-dimensional structures and tools at a scale much too small for even the deftest robots or nimblest human hands to manipulate.
