Scientists Create Unique Nanoparticles By Staff A U.S. research team has created nanoparticles that can deliver medicines deep into the lungs and infiltrate cancer cells while ignoring normal cells. The tiny, biodegradable particles were created using a technique invented by a Princeton University-led team. More than 100 times thinner than a human hair, the particles can be loaded with medicines or imaging enhancing agents. "The intersection of materials science and chemistry is allowing advances that were never before possible," said Robert Prud'homme, a Princeton chemical engineering professor and the director of a National Science Foundation-funded team of researchers from Princeton, the University of Minnesota and Iowa State University. "No one had a good route to incorporate drugs and imaging agents in nanoparticles."
