Derek Lowe: There's a paper in the preprint section of the ACS journal Nano Letters that's one of the neatest things I've seen in a while. Jim Tour's group at Rice has been working in this area for quite a while now, and they now report something they call a "nanocar."
It's easy to dismiss this work as a stunt, which is what I once did with one of Tour's other ideas. But this is the beginning of the real thing. A larger, more functionalized version of the nanocar might carry other molecules along and dump them at will, which is what this group seems to be working on now. These are small steps toward controlled nanoscale delivery, which is a small step toward a nanotech assembler.
