Technique has potential to detect cancer

Hank Hogan

A team of researchers wants to use gold to mark a spot where a tumor in the earliest stage of breast or prostate cancer exists. To that end, a group from the University of Texas Medical Branch in Galveston, from Fairway Medical Technologies in Houston, from the Mayo Clinic College of Medicine in Jacksonville, Fla., and from the University of Michigan in Ann Arbor, used engineered gold nanorods as a contrast agent for a laser optoacoustic imaging system. In the in vivo optoacoustic experiment, gold nanorods were injected subcutaneously into the lower abdomen and detected from the back...Read full article
