Researchers have been hard at work for the past few years trying to build computer chips using self-assembling circuitry built of molecules -- meaning that they're incredibly teensy. Some researchers at MIT seem to have gotten the hang of this nano-business, according to a paper just published in Nature and Nanotechnology (which also happens to be our favorite magazine after Offset Print Enthusiast). They've made a pretty good leap forward recently, by using electron-beam lithography to make patterns of nano-posts on a silicon chip, which are deposited with special polymers, resulting in a hookup between the polymer and the posts which arrange themselves into useful p
