Gold nanoparticles, radiation combo may slow Alzheimer's
Chemists in Chile and Spain have identified a new approach for the possible treatment of Alzheimer's disease that they say has the potential to destroy beta-amyloid fibrils and plaque -- hypothesized to contribute to the mental decline of Alzheimer's patients. The researchers say the new technique, which they call a type of "molecular surgery," could halt or slow the disease's progress without harming healthy brain cells.
