Nano Drugs -- Just what the doctor ordered?

Is this cool and creepy all at the same time or what? Imagine little microscopic robots entering your body and delivering much needed medicine only to the cells that need it -- wow.

Delivering a dose of chemotherapy drugs to specific cancer cells without the risk of side affects to healthy cells may one day be possible thanks to a nanoscale drug delivery system being explored by researchers at the U.S. Department of Energy's Ames Laboratory. Using tiny silica particles call mesoporous nanospheres to carry drugs inside living cells, Ames Laboratory chemist Victor Lin is studying different methods to control whether or not the particle delivers its pharmaceutical payload.
