(Brown University) A team led by a Brown University chemist has created the smallest iron oxide nanoparticles to date for cancer detection by magnetic resonance imaging.

The magnetic nanoparticles operate like tiny guided missiles, seeking and attaching themselves to malignant tumor cells.

Once they bind, the particles emit stronger signals that MRI scans can detect.
