    New Technique Sees Into Tissue At Greater Depth, Resolution
    DURHAM, N.C. By coupling a kicked-up version of microscopy with miniscule particles of gold, Duke University scientists are now able to peer so deep into living tissue that they can see molecules interacting. If future studies in animal models prove fruitful, the researchers believe that their new approach can have a wide spectrum of clinical applications, from studying the margins of a tumor as it is removed from the body to assessing the effects of anti-cancer agents on the blood vessels that nourish tumors. The Duke bioengineers combined tightly focused heat with optical coherence tomography (OCT), which has often ...
