Subject: Purdue's Gold Nanorods Brighten Future For Medical Imaging

Researchers at Purdue University have taken a step toward developing a
new type of ultra-sensitive medical imaging technique that works by
shining a laser through the skin to detect tiny gold nanorods injected
into the bloodstream.
In tests with mice, the nanorods yielded images nearly 60 times
brighter than conventional fluorescent dyes, including rhodamine,
commonly used for a wide range of biological imaging to study the
inner workings of cells and molecules.
