MOORE I'm a bit of a skeptic on molecular chips. Maybe I'm getting old. It's hard for me to see how those billions of transistors can be interconnected at that level...
...MOLECULAR AND DOT COMPUTERS Other exotic designs include the molecular computer and the quantum dot computer (which replace the silicon transistor with a single molecule and a single electron, respectively). But these approaches face formidable technical problems, such as mass-producing atomic wires and insulators. No viable prototypes yet exist...
Nanotechnology is the science of creating molecular-size machines that manipulate matter one atom at a time. The name comes from nanometer--one one-billionth of a meter--which is roughly the size of these tiny devices...
...MOLECULAR MEDICINE Streaming through the body by the billions, nanobots could chip plaque from arteries, gang up on bacteria and viruses, scour toxins from the bloodstream, repair broken blood vessels--and dozens of jobs doctors haven't dreamed...
...robots? We are making progress, both from the bottom up and from the top down. At one end, researchers are taking apart the simplest living bacteria--mycoplasmas--whose genome can be stored in less than a quarter of a megabyte, to better understand the process of life at the molecular level. Meanwhile, computer programs that reproduce and evolve are starting to exhibit behaviors we expect from simple living creatures, such as interaction with complex environments and sexual reproduction. Artificial life forms that "live" inside computers have evolved to the point where they can chase prey, evade predators and compete...
