MRI On The Nanoscale
Scientists at IBM’s Almaden Research Center, in San Jose, Calif., report the first nanometer-scale magnetic resonance imaging of a biological sample. At such length scales, MRI could be used to image the three-dimensional structure of individual macromolecules and complexes, they note. Conventional MRI microscopy is limited to the micrometer scale. The IBM team, led by Dan Rugar, manager of nanoscale studies, improved the spatial resolution by combining magnetic resonance . . .
