I read about some big news on using nanoparticles for getting rid of cancer. I can't find the article right now but it had to do with nanoparticles which could safely and specifically go to cancer cells and with a certain frequency it would heat up the beads and kill the cancer cell. That was pretty cool, I did a half ass job of explaining it though. Really though, most the stuff I see for nanotechnology is in the field of cancer research.
