Scientists are wrestling with individual atoms to develop molecule-sized computers, tiny cancer-fighting robots that travel the bloodstream ... and stain-resistant trousers.
Nanotechnology -- the science of manipulating materials billionths of a meter wide -- has emerged as a promising new field that could lead to stunning advances in years to come.
Boosters claim that nanotech-derived products may someday cure disease, slow the aging process and eliminate pollution.
But for now, the human race will have to settle for tennis balls that keep their bounce longer, flat-panel displays that shine brighter, and wrinkle-free khaki slacks that resist coffee stains.
"People are saying, 'Geez, this isn't Star Trek yet, this is just pants that don't stain,' but you've got to start somewhere," said Howard Lovy, news editor of the nanotech industry journal Small Times. "I'm wearing nano-pants as we speak."
Those stain-resistant pants and bouncy tennis balls have their advantages, thanks to a fundamental principle of small science: Different scales lead to different results. Just as a silver necklace may sparkle against your skin but tiny silver particles in your bloodstream will turn your skin blue, common substances like sunscreen and rubber take on entirely different characteristics when assembled at a molecular level.
