And this is what I think is the magic of fluorescence.

So we're coming up with these beautiful fluorescent dyes, and you saw one on the first page in this podcast.

So that's the beauty of having a tumor that's labeled with fluorescent molecules.

It's day already.

All day long.

Doc, it's almost morning. Queen of clubs.
