Tumor Elimination? Tumor Illumination.
I'm Bob Karson with the discovery files -- new advances in science and engineering from the National Science Foundation.
You might want to say this isn't brain surgery but in this case, it is; at least a new method that may make brain surgery easier, less invasive and more effective. Scientists at Ohio State are getting "glowing" reviews on a particle they've developed that could have tumors "light up" for surgeons and be more clearly defined with an MRI scan.
The tumors they're looking at are lethal ones called glioblastomas. Very hard to see and remove by surgeons. The team is combining two tiny particles -- one magnetic, one fluorescent -- to create composite particles to be injected into the bloodstream. Not only will they show the tumor in an MRI with greater definition and contrast, under special light, to the surgeon the tumor will appear to glow a different color than surrounding healthy tissue. Remove say, all the green and you've removed the entire tumor.
The researchers have proven that this composite particle can be created, except that up to now they've been using fluorescent cadmium telluride particles which are quite toxic to animals and humans. Their new research involves trying to make carbon-based fluorescent particles. Same affect no toxicity.
Tumors that glow a different color -- lighting the way to what could be the future of brain surgery.
