Magnetic nanotags detect cancer much earlier than current methods

Extremely sensitive nanosensor chips are being developed by Stanford University researchers in an attempt to detect the early signs of cancer, called biomarkers, in humans. The researchers say their sensor is around 1,000 times more sensitive than current technology and is accurate regardless of which bodily fluid is being analyzed. It can also detect biomarker proteins over a range of concentrations three times broader than any existing method. It is forecast that earlier detection of cancer biomarkers will lead to improved survival rates among cancer sufferers. Read More
Sugar-coating nanoparticles to tempt cancer cells brings dual benefits

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.

Treating tumors by blasting nanotubes with a laser

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.
