Purdue's gold nanorods brighten future for medical imaging
...ining 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, com......'t go but a few millimeters deep. But by using the nanorods we can tune them to react to the infrared lasers, ... as strongly. By conjugating, or binding, the gold nanorods to an antibody for EFGR, suitably named anti-EFGR, researchers were able to get the nanoparticles to...
