A day later, the "activatable" compound was found only in lung tumors, while the "always on" one glowed on lung tumors, normal lung tissue and the heart.
The findings showed the compound was 99 percent accurate in tumor detection for HER2-positive tumors, while the "always on" control was accurate less than 85 percent of the time.
In another experiment, the researchers re-engineered the compound so it successfully detected live ovarian cancer cells that had spread to the tissue lining the walls of the abdomen in mice.
