Nanotech Kills Cancer

Researchers at Stanford have developed nanotubes that can enter cancer cells by attaching folate to them, a vitamin that normal cells do not absorb, but cancer cells do. Once in the cancer cells, the nanotubes are destroyed by infra-red light. Infra-red light passes through the body harmlessly, but heats the carbon nanotubes until they burn up, taking the cancer cells with them. Thus far, the work has all been done in controlled lab circumstances, but the process sounds solid and feasible for use in living subjects. Full story on BBC news.
