BRIGHTs bind to biomarkers of disease and light up to reveal their location

Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location.

Radioactive gold nanoparticle treatment safe and effective in dogs with prostate cancer

Currently, large doses of chemotherapy are required when treating certain forms of cancer, resulting in toxic side effects. The chemicals enter the body and work to destroy or shrink the tumor, but also harm vital organs and drastically affect bodily functions. Now, scientists at the University of Missouri have proven that a new form of prostate cancer treatment that uses radioactive gold nanoparticles, and was developed at MU, is safe to use in dogs.

UMass Amherst develops 'chemical nose' array to detect metastatic cancers

In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

Gold nanoparticles with slight positive charge work collectively to unravel DNA's double helix

New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA's double helix. This finding has ramifications for gene therapy research and the emerging field of DNA-based electronics.

Electronic nose and optoacoustics improve diagnosis of prostate cancer

Chances of survival of prostate cancer depend strongly on the stage at which the disease is diagnosed. Now scientists have developed new methods relying on an electronic nose and optoacoustics to improve the diagnosis techniques and avoid fatal treatment delays

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.

Delivering chemotherapy drugs with nanobubbles more deadly to cancer cells

Using light-harvesting nanoparticles to convert laser energy into "plasmonic nanobubbles," researchers at Rice University, the University of Texas MD Anderson Cancer Center and Baylor College of Medicine (BCM) are developing new methods to inject drugs and genetic payloads directly into cancer cells.

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.

New transfection method changes genetic material of cancer cells

Researchers at Polytechnique Montr-al have succeeded in changing the genetic material of cancer cells using a brand-new transfection method. This major breakthrough in nanosurgery opens the door to new medical applications, among others for the treatment of cancers.

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.
