Nanodevices for the Brain could thwart formation of Alzheimer’s Plaques

Researchers designed a nanodevice with the potential to prevent peptides from forming dangerous plaques in the brain in order to halt development of Alzheimer’s disease. Alzheimer’s disease is the sixth leading cause of death in the United States, affecting one in 10 people over the age of 65. Scientists are engineering nanodevices to disrupt processes in the brain that lead to the disease.

People who are affected by Alzheimer’s disease have a specific type of plaque, made of self-assembled molecules called β-amyloid (Aβ) pep...
