NANOTECHNOLOGY -- engineering substances down to billionths of a meter in size -- holds out such promise of providing super-strong materials or desalinating water inexpensively that no one wants to put a red light in its way. But there are enough safety questions to justify more yellow lights than either industry or government has yet deployed.
