Credit: Hemera/Thinkstock It's a popular goal in nanotechnology these days: using tiny particles as containers to ferry drugs to tumors, among other targets. But immune sentries called macrophages quickly spot foreign invaders and gobble them up. Now, a team of Pennsylvania researchers has found a way to give particles a molecular "passport" that gets them past the sentries in mice, where the particles then deliver their lethal cargo to tumors and help destroy them. That success...
