"C, a much lower temperature than was previously necessary for making nanotubes. nanotubes grown this way self-organize into ropes.These have promising engineering applications. In the techniques used at Rice University a laser is aimed at a block of graphite, vaporizing the graphite. Contact with a cooled copper collector causes the carbon atoms to be deposited in the form of nanotubes.The nanotube "felt" can then be harvested.

"Carbon nanotubes spots cancer lying in remission and determines if, and when it may flare up, and identifies new tumors as well. Development expected by 2008. - Lab-on-a-Chip promises early detection of cancer, heart disease, Alzheimer's and other ills. Patients will one day walk into their doctor's office with this handheld device, give a few drops of blood, and in minutes, receive a complete health diagnosis." - Bill Sardi, You Don't Have to be Afraid of Cancer Anymore (Get the book.)

"Photovoltaic cells made from nanotubes are more flexible, lighter in weight, and potentially less expensive than traditional silicon solar cells. In theory, we'll be able to do a lot more with them: embed them in fabrics, wrap them around curving structures, and paint them on walls and roofs. ¦ The development of nanoscale wires able to turn heat into electricity and vice versa will mean refrigerators that can operate without pumps or chemicals, solar panels that are able to extract power from heat or light, and even vehicles that can draw power from the heat of engines." - Alex Steffen, Worldchanging: A User's Guide for the 21st Century (Get the book.) "In mid-2005, however, researchers at the University of Texas, Dallas, and the Commonwealth Scientific and Industrial Research Organization in Australia came up with a way to make strong, stable macroscale sheets and ribbons of multiwall nanotubes at a rate of 7 meters (23 feet) per minute. The team described potential applications of the process as including transparent antennae, high-quality electronic sensors, supercapacitors and batteries, light sources and displays, solar cells, artificial muscles, tissue-growth scaffolding, and much more." - Alex Steffen, Worldchanging: A User's Guide for the 21st Century (Get the book.) "And the metals industry: is it in the mining and smelting business, or is it in the materials business, providing high-quality ingredients for the modern economy, whether those are recycled metals, new substances (like carbon nanotubes) or better design? Mining or materials? We could ask the question of any industry. Is the automobile industry in the business of selling cars, or of moving people? Is agriculture in the business of raising massive amounts of food, or of providing nutrition and healthy soils?" - Alex Steffen, Worldchanging: A User's Guide for the 21st Century (Get the book.) "And researchers are finding ways to reduce the toxicity of the most dangerous nanotubes dramatically: a recent minor modification reduced the cytotoxicity (the dose at which 50 percent of affected cells die within forty-eight hours) by more than 10,000 times, making the modified nanotube essentially nontoxic. jc The Precautionary Principle Writers of bad science fiction and easily startled doomsayers love the idea of out-of-control nanomachines—machines that self-replicate and devour everything in their path." - Alex Steffen, Worldchanging: A User's Guide for the 21st Century (Get the book.)

"Physicists at the University of California, Berkeley have peeled the tips off carbon nanotubes to make seemingly frictionless bearings so small that some ten thousand would stretch across the diameter of a human hair The bearings are telescoping nanotubes, with the inner tube spinning about its long axis. When sliding in and out, they act as springs. Potential applications include frictionless motors, which might run at high speed without lubricants or cooling systems. (John Cumings and Alex Zerrl, UC Berkeley; www.berkeley.edu/news/media/releases/2000/07/27_nano.html) Robotics." - Douglas Mulhall, Our Molecular Future: How Nanotechnology, Robotics, Genetics and Artificial Intelligence Will Transform Our World (Get the book.)

"A place where nanotechnology seems to be progressing rapidly is in the construction of so-called carbon nanotubes. When placed in a strong electric field, carbon atoms can arrange themselves into sheets, which then fold up into a set of nested tubes. A set of tubes typically will contain up to twenty individual tubes that are up to 20 nanometers across and some thousands of nanometers long. Some researchers are trying to find ways of keeping carbon atoms happy enough to grow nanotubes several feet long." - James Trefil, 101 Things You Don't Know About Science And No One Else Does Either (Get the book.)
