The light that the fluorescence emits can go through tissue.

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

Well we took the manuscript, and we decided to image it in X ray fluorescence imaging.

And the cool thing about fluorescence is that it's not only bright, it actually can shine through tissue.

So I said, wouldn't it be great if we could find a way to see nerves with fluorescence?

And when we made a solution of this, tagged with the fluorescence and injected in the body of a mouse, their nerves literally glowed.

What needs to happen now is further development of our technology along with development of the instrumentation that allows us to see this sort of fluorescence in the operating room.

And so by applying ancient DNA sequencing and protein mass spectrometry technologies to ancient dental calculus, we can generate immense quantities of data that then we can use to begin to reconstruct a detailed picture of the dynamic interplay between diet, infection and immunity thousands of years ago.

I won't go into this very much, but our technology, besides being able to tag tumor and metastatic lymph nodes with fluorescence, we can also use the same smart three part molecule to tag gadolinium onto the system so you can do this noninvasively.
