Nano World: How nanotubes enter cells

Charles Q. Choi: Physical chemist Hongjie Dai's team at Stanford University in California are exploring carbon nanotubes as therapeutic agents. For instance, while biological tissue is transparent to near-infrared light, carbon nanotubes absorb it, and Dai and his colleagues in August reported that by tagging carbon nanotubes so that they would specifically latch onto cancer cells and shining near-infrared lasers on them, they could kill just cancer cells without harming normal tissue.
