A NEW nanotechnology nasal spray is being developed that could transform the early detection and treatment of Alzheimer's.
The device shoots tiny magnetic particles into the nose which enter the bloodstream and are carried to the brain.
Each particle is fused to an antibody that targets and binds to rogue molecules believed to play an early role in the disease.
Magnetic resonance imaging (MRI) can detect both the particles and the molecules.
Details of the research were presented yesterday at the annual meeting of the Society for Neuroscience in New Orleans,.
Lead scientist Dr William Klein, from Northwestern University, Chicago, said: "This technology is a promising tool for early AD diagnosis."
