New test accurately detects aggressive prostate cancer

One in six men will be diagnosed with prostate cancer during his lifetime, the second leading cause of death among men in the United States. It's a serious problem and current diagnostic tests aren't very specific. But a research team at the University of Central Florida NanoScience Technology Center has found a more accurate test that not only determines whether a patient has prostate cancer, but also how aggressive it is.

Gold nanoparticles used to introduce chemical residues into the immune system

Developing a drug or vaccine requires a delicate balancing act with the immune system. On one hand, medications need to escape detection by the immune system in order to perform their function. But vaccinations - de-activated versions of a disease or virus - need to do the reverse. They prompt the immune system to create protective antibodies.

Scientists use gold-filled silicon wafers to target and burn breast cancer cells

By shining infrared light on specially designed, gold-filled silicon wafers, scientists at The Methodist Hospital Research Institute have successfully targeted and burned breast cancer cells. If the technology is shown to work in human clinical trials, it could provide patients a non-invasive alternative to surgical ablation, and could be used in conjunction with traditional cancer treatments, such as chemotherapy, to make those treatments more effective.

Researchers use gold nanorods to distinguish brain tumor from healthy tissue

"It's not brain surgery" is a phrase often uttered to dismiss a job's difficulty, but when the task actually is removing a brain tumor, even the slightest mistake could have serious health consequences. To help surgeons in such high-pressure situations, researchers from Prof. Adam Wax's team at Duke University's Fitzpatrick Institute for Photonics and Biomedical Engineering Department have proposed a way to harness the unique optical properties of gold nanoparticles to clearly distinguish a brain tumor from the healthy, and vital, tissue that surrounds it.
