Tiny particles may help surgeons by marking brain tumors
Date:4/29/2010

er's study provided convincing proof that a particle with dual properties can be formed. However, these multi-functional particles can't be used for animal or human testing because the fluorescent particle, cadmium telluride, is toxic.

"We're currently working on an alternative fluorescent particle which is composed of carbon. This will eliminate the complications that arise with ingesting the cadmium telluride particles," Winter said.

Patients with a specific form of deadly brain tumor, glioblastoma, could benefit from Winter's work. Glioblastomas are usually located in the temporal, or frontal lobe of the brain, and tumors located there are difficult to see and remove.

Combining the two particles could provide doctors with help both before and during the surgery to remove a brain tumor, Winter said.

One of the successes in creating the new nanocomposite particle was how they did it, Winter said. It is normally difficult to combine particles like these, a process known as doping.

The Ohio State researchers pursued an approach which had not been attempted before. They chose to bind their fluorescent particle on top of their magnetic particle at extremely high temperatures.

The key is that our synthesis is done at pretty high temperatures about 350 degrees Celsius (around 660 degrees Fahrenheit)," Winter explained. "The synthesis was unexpected, but cool at the same time, and we were excited when we saw what we got."
