Treating Cancer with Nano-bio Technology
Argonne's Center for Nanoscale Materials Scientist Elena Rozhkova, along with researchers from the University of Chicago, have developed a way to attach a antibody to nanomaterial titanium dioxide and kill brain cancer cells.

The bare titianium dioxide nanoparticle bonds with an antibody and attaches itself to brain cancer cells. When exposed to concentrated white light, the titanium dioxide creates free radicals of oxygen that causes the cancer cells to die.
