Balaji Panchapakesan at the University of Delaware figured out a less risky way to get rid of tumors. He came up with the idea of Cancer Nanobombs. Cancer Nanobombs are tiny carbonNanotubes filled with water, which are injected into the area with the tumor. Then a laser light is zapped into the area causing the water inside the Nanotube to boil thus causing the Nanobombs to explode and kill any nearby cells.
Sure the Nanobombs will kill other cells along with the tumor cell but its better than the side effects of chemo.
