Chemists create red fluorescent dyes that may enable clearer biomedical imaging | The new dyes are based on boron-containing molecules that were previously too unstable for practical use.


MIT chemists designed a fluorescent molecule they hope could be used for applications such as generating clearer images of tumors. The dye is based on a borenium ion — a positively charged form of boron that can emit light in the near-infrared.
