Researchers at the Winship Cancer Institute (part of the Emory-Georgia Tech Center for Cancer Nanotechnology Excellence) are working to develop clinically viable ways to detect biomarkers that indicate a patient's risk of developing cancer. They have developed a nanotechnology-based method to detect a number of molecular markers at the same time ("multiplexed") on a single tissue specimen with the use of quantum dot particles as fluorescent stains. In the above image, the method is used with colon tissue in an effort to identify markers which are predictive of increased risk of developing colon cancer.
