A team of scientists is using nanotechnology to invent news ways for doctors to find even the smallest cancerous tumors, and treat them before they grow.
Michael Sailor, a chemist at the University of California, San Diego, is part of this team. He and his colleagues are working to create microscopic nanoparticles - tiny bits of magnetic iron oxide only a few atoms in diameter - that target and mark small tumors.
This process would make the tumors easier for doctors to detect on MRI scans. And that's important because one of the best ways to treat cancer is to detect and destroy tumors early on.
