“A new chip, developed at Stanford University's Center for Magnetic Nanotechnology, has the potential to detect any of seven different types of cancer in their early developmental stages. Magnetic technologies give the biomarker chips increased sensitivity as compared to traditional fluorescent detection methodology. In some cases, this could be as much as 400 times more sensitive.
The device consists of 64 magnetic sensors known as Spin Valves. Each of these sensors is coated with a cancer-specific antibody, which will attach to a specific cancer protein. Using two sets of specially prepared antibodies, the tumor proteins are bound to magnetic nanoparticles so that the magnetic sensors can detect the cancerous proteins.
