Nanotechnology Researchers in such fields as physics, chemistry, materials science, and computer science are using nanotechnology, which involves manipulating materials at the atomic or molecular level to build machines, including microscopic, massively parallel computers that will be more powerful than the supercomputers of today. Scientists could program these computers to replicate themselves. Doctors could then inject them into a human body to hunt down and destroy deadly viruses or cancers. Scientists have already used the technology to create carbon nanotubes that are 100 times stronger and 100 times lighter than steel. Using various ways to interweave mold execute the nanotubes, computer manufacturers can fashion them into insulators, conductors, or semiconductors. In late 2001, IBM announced that its scientists had built a computer circuit made of nanotubes, the first logic circuit consisting of a single molecule. Although the circuit can perform only one simple operation (true/false), the development was nevertheless seen as a giant advancement in

Unformatted text preview: the field of computer circuitry because it could eventually lead to the creation of processors that hold up to 10,000 times more transistors in the same amount of space. In 2003, a Woburn, Massachusetts, company called Nantero Inc. introduced a nonvolatile random-access memory (NRAM) chip that uses single-walled carbon nanotubules only 20 billionths of a meter wide. The miniscule tubules are arranged in a grid that holds 5 billion bits of data in one square centimeter, which is several times the density of current high-capacity memory chips. Because the NRAM chips are about five times faster than todays speediest memory chips and they are nonvolatile, the chips are considered a thrilling development for use as flash memory in digital cameras and cell phones. The federal government predicts that by the year 2015, nanotubes and the field of nanotechnology will be a trillion-dollar-a-year industry and that one in four jobs will be nano-related....
