Duke University’s Phillip Hughes is developing compounds that combine a protein inhibitor with other types of molecules in hopes of selectively targeting tumors for imaging and possibly for destruction. To save money, the group decided to make their own near-infrared fluorescent dyes to connect with the inhibitor. One such compound, the synthetic Cy-7 dye shown, goes from green in solution to a metallic looking gold as the solvent evaporates.
