Researchers believe nanoparticles hold the promise of battling cancer without the damaging side effects of chemotherapy or radiation treatment. They have discovered that coating minuscule balls of iron oxide with sugar molecules not only makes them particularly attractive to resource-hungry cancer cells, it also makes them more effective by allowing them to get close to each other, but not too close to render treatment ineffective.  Read More

Current heat treatments for human tumors, such as radiofrequency, have shown promising results over the last couple of decades, even though they apply only a single-point of heat to the tumor. However, a new technique could prove much more effective by using nanotubes to apply heat throughout the tumor. Scientists found that by injecting the man-made, microscopic carbon tubes into tumors and heating them with a quick, 30-second zap of a laser, they were able to effectively kill kidney tumors in nearly 80 percent of mice.  Read More
