TREATING CANCER WITH NANOTECHNOLOGY: “In a study with breast cancer in mice, a nanotech cancer therapy suppresses tumor growth with minimal side effects. Taking advantage of the fact that the blood vessels in tumor tissue are leakier than in normal tissue, carbon nanotubes of the right size and with the proper chemical coating deliver more tumor-killing drug to tumors, while sparing normal tissue. In future experiments, the researchers may add molecules that specifically target tumor cells to achieve even greater specificity.”
