one giant step for humanity to kill cancer

Tetsuo Nagano's group at Tokyo University does research on fluorescent pigments, to analyze the molecules in living cells. In the course of this research, the Group has developed a new red fluorescent pigment, called Tokyo Magenta.
"In terms of small organic molecules, most fluorescent pigments are fluorescein-based, and those all fluoresce green. Of course, all kinds of pigments have been made, with different wavelengths giving red, orange, or yellow. But fluorescein pigments are used because they have superior properties for bioscience research. They're highly soluble in water and have low toxicity. So, while that kind of green pigment is used often, useful fluorescent pigments with other colors haven't really been produced."Tokyo Magenta is based on a green fluorescein pigment developed previously by the Nagano Group. By replacing oxygen atoms with silicon, the excited states of the m
