Date posted: 24/12/2009 Cornell researchers are devising methods to detect the magnetic fields of individual electrons and atomic nuclei, which they hope to use to make a nanoscale version of magnetic resonance imaging. In biochemistry, shape is everything. Because of the shape of their binding sites, hormones can attach to cell membranes to send signals inside, and viruses can open up paths to invade. But understanding the structure of complex molecules, sometimes made of tens of thousands of atoms, is no easy task. Existing microscopes, even the world's best electron microscopes, can't resolve atomic details of organic material. Researchers at Cornell are changing that: They are devising methods to detect the magnetic fields of individual electrons and atomic nuclei, which they hope to use to make 3-D images -- a nanoscale version of magnetic resonance imaging. Their new approach can detect a tiny force called electron spin to a sensitivity scale of about 400 electrons.
