Tagging tumors with gold: Scientists use gold nanorods to flag brain tumors
Date:10/12/2011

Shining the tuned frequency of light on the sample revealed bright points where the tumors lurked. The tunability of the gold nanoparticles is important, says team member Kevin Seekell, because it allows researchers to choose from a window of light frequencies that are not readily absorbed by biological tissue. It might also allow researchers to attach differently tuned nanoparticles to different antibodies, providing a way to diagnose different types of tumors based the specific surface proteins the cancer cells display. Future work by the team will also focus on developing a surgical probe that can image gold nanoparticles in a living brain, Seekell says.
