A quick sniff of a nasal spray sends microscopic metal particles into the brain, where they target and destroy the damaging proteins of Alzheimer's disease. No Alzheimer's?
No problem—the metal particles pass out of the body safely. Such is the promise of technology being developed by neuroscientist William Klein and nanotechnologist Vinayak Dravid of Northwestern University.
The pair has invented a nanotech-based early-detection system that might one day deliver targeted treatments.
