Alzheimer’s disease can be identified much before you see the usual symptoms, says a Northwestern University team of scientists and engineers. The team has invented a noninvasive magnetic resonance imaging device, which coupled a magnetic nanostructure with an “antibody that seeks out the amyloid beta brain toxins,” going on to the beginning of Alzheimer’s disease.

The MRI scans of the brain can detect the toxins that have gathered as dark areas, due to the associated magnetic nanostructures. A new brain imaging method to identify the toxin leading to Alzheimer’s disease is available now, according to neuroscientist William L. Klein, leader of the research team, along with materials scientist Vinayak P. Dravid.
