Smaller

S38, E3: How small can we go? Could we one day have robots taking “fantastic voyages” in our bodies to kill rogue cells? The triumphs of tiny are seen all around us in the Information Age: transistors, microchips, laptops, cell phones. Now, David Pogue takes NOVA viewers to an even smaller world in Making Stuff Smaller, examining the latest in high-powered nano-circuits and micro-robots that may one day hold the key to saving lives and creating materials from the ground up, atom by atom. Pogue explores the star materials of small applications, including silicon, the stuff of computer chips, and carbon, the element now being manipulated at the atomic level to produce future technology. “Smaller” and more portable stuff has already revolutionized the way we live. The nanotechnology to come could change the face of medicine, with intelligent pills that know what medicine to release into the body and treat patients from the “inside” based on changing needs; robots that repair damaged body parts; and more.
