In a paper published in Advanced Materials, the Belcher Lab demonstrated recent advancements to their imaging system. First, they paired short-wave infrared organic dye molecules with gold nanorods to increase the brightness of their fluorescent probes. Then, collaborating with the Hammond and Irvine groups, they designed three different surface coatings to help target the fluorescent probes to tumors. In ovarian cancer mouse models, the researchers showed that the probes are not only brighter, but that all three coatings target efficiently to tumors, making them ideal for use in real-time imaging guided surgery.
