Nanotech medicine
Nanotechnology has the potential to improve medicine in many areas. A pair of research developments moves nanotechnology treatments for cancer and degenerative eye problems closer to reality.
Researchers from Harvard Medical School and the University of Connecticut have developed a cancer treatment that uses nanoparticles to encapsulate light-sensitive molecules. Nanoparticles are bits of matter not much bigger than molecules. When a nanoparticles is absorbed by a cell it releases the encapsulated molecules. Exposure to visible light makes the molecules toxic, killing the cells. The nanoparticles completely eradicated several types of cancer tumors in mice, according to the researchers.
