A revolution in heart surgery
While procedures with medicated stents are being done now, nanotechnology is likely to help cardiac patients in the future, says Denis Buxton, associate director of the heart research program at the National Heart, Lung and Blood Institute in Bethesda. Mr. Buxton holds a doctorate in biochemistry.
For instance, he expects that nanotechnology will deliver drugs exactly where they are needed in the body by targeting the medication to a specific site. He also anticipates that nanotechnology will be used in molecular imaging, which will better identify diseases.
