Magnetic Medicine: Nanoparticles target cancer-fighting immune cells

Using tiny particles designed to target cancer-fighting immune cells, researchers have trained the immune systems of mice to fight melanoma, a deadly skin cancer. The experiments represent a significant step toward using nanoparticles and magnetism to treat a variety of conditions, the researchers say. They also note that in addition to its potential medical applications, combining nanoparticles and magnetism may give researchers a new window into fundamental biological processes.
