Technique uses well-known dye to watch amyloid plaques in the brain
(PHYSorg.com Physics)

While amyloid plaques have long been closely associated with mechanisms driving Alzheimer`s disease, visualizing how amyloid proteins assemble continues to prove difficult. The nanometer-sized amyloid fibrils are only a fraction of the size that the best light microscopes are able to resolve. New work repurposing one of the oldest known reagents for amyloid looks to help provide a clearer picture of how fibrils come together.
