Narrator: This is Science Today. The 2008 Nobel Prize in Chemistry was shared by University of California, San Diego researcher Roger Tsien, who has dedicated his career to the development and application of a fluorescent protein that can be used as a glowing marker to monitor cellular function that's beyond what the human eye can see.
Tsien: Our work is often most described as building and training molecular spies - molecules that will enter cell or an organism and report back to us what conditions are - what's going on in the biochemistry while the cell is still alive.
Narrator: Tsien's lab has engineered dyes that can infiltrate their target without harming or disrupting the cell. Tsien is now interested in imaging and treating cancer using this technique.
Tsien: Moving our work from cellular and molecular, low-level high resolution work on single cells and moving that toward whole animals and maybe real people who need to be imaged, then diagnosed and hopefully we'll have some contribution toward helping cure them.
