Nanotechnology is changing the way we treat disease. Cutting-edge treatments will use materials that are as small (or even smaller!) as the tiniest parts of cells in the body. Researchers think that nanomedicine will work only on targeted cells, and will have fewer side effects on the rest of the body.
When gold nanoshells are injected into the bloodstream, they travel through healthy blood vessels but easily slip through the leaks found in tumor blood vessels and collect in the tumors.
A laser shines light through skin and tissue (without damaging them!) and into each tumor, where the nanoshells absorb the energy and heat up.
The heat from the nanoshells destroys the tumor cells.
