Date posted: 14/01/2009 Magnetic resonance imaging, or MRI, is a mainstay of medicine and neuroscience research. It can noninvasively probe deep inside tissues and gives information on the presence of specific chemicals. But because the magnetic forces that it detects are so tiny, MRI isn't very sensitive: it typically reveals structures on the millimeter to submillimeter scale. Now researchers at IBM Almaden Research Center, in California, have developed an MRI scanner with resolution 100 million times better than that--good enough to image individual viral particles. With further refinements, the technique could one day be used to generate 3-D images of individual molecules. "The dream of imaging a single molecule is something that keeps chemists up at night," says John Marohn, an associate professor of chemistry and chemical biology at Cornell University. "If you had this tool, there's no end of things that you could do with it, and there's no end to the good that would come of it."
