Meanwhile, nanotechniques are already being used to make sunscreens, stain-resistant fabrics, and composite materials in cars. Soo n they will be used to make computers and storage devices of extremely small size.And some of the long-anticipated “miracle” products have started to appear as well. In 2002 one company was manufacturing self-cleaning window glass; another made a nanocrystal wound dressing with antibiotic
and anti-inflammatory properties. At the moment nanotechnology is primarily a materials technology, but its potential goes far beyond that. For decades there has been speculation about self-reproducing machines. In 1980 a NAS A paper discussed several methods by which such machines could be made. Ten years ago, two knowledgeable scientists took the Within fifty to a hundred years, a new class of organisms is likely to emerge. These
