Painting brain tumors with nanoparticles may help defeat cancer

Nanotechnology is preoccupying science to the point where it's starting to seem unremarkable. But a group of researchers from the University of Washington has released findings that could profoundly improve the chances of surviving brain cancer. The team has developed a fluorescent nanoparticle that is capable of penetrating – for the first time – the blood-brain barrier without damaging it. The fluoro nanoparticle targets tumors using a derivative of scorpion venom and enables precise imaging of the size and location of cancerous growths. When the particles meet the tumor, they light up like Christmas.
