Nanotech Exterminators: Scientists Capture, Destroy Cancer Cells in Bloodstream, University of Arkansas Study

medGadget -- A research team led by folks from the University of Arkansas for Medical Sciences used a combination of preprogrammed nanoparticles and external magnets to capture and collect circulating tumor cells (CTCs) within blood vessels. Additionally, they were able to use laser light to kill CTCs that were accumulated under the skin by magnets placed near the surface.
