A new molecule designed to seek out and label cancer cells could help guide surgeons to hidden pockets of disease--a technology that could one day allow for more complete tumor removal and increase a patient's chances of survival. The molecular label, developed by researchers at the University of California at San Diego (UCSD), works in two ways. It tags cancer cells with a fluorescent marker to highlight tumors for identification and removal during surgery, and it contains a magnetic marker. (source: technologyreview.com)
