1. We designed and tested an imaging material that can be used to detect Alzheimer disease (AD) by magnetic resonance imaging (MRI).
2. The material consists of magnetic iron nanoparticles coated with curcumin that binds the amyloid plaques in AD brain.
3. After injecting the nanoparticles, MRI distinguished AD from control model mice.
4. In examining slices of brains, the nanoparticles were highly concentrated at the plaques and significantly coincided with the dark spots seen on MRI.
5. The nanoparticles were non-toxic to cells grown in dishes.
