IBM scientists, in collaboration with the Center for Probing the Nanoscale at Stanford University, have demonstrated magnetic resonance imaging MRI with volume resolution 100 million times finer than conventional MRI.
For more than a decade, IBM scientists have been making pioneering advances in
MRFM. Now, the IBM-led team has dramatically boosted the sensitivity of MRFM and combined it with an advanced 3D image reconstruction technique. This allowed them to demonstrate, for the first time, MRI on nanometer-scale biological objects. The technique was applied to a sample of tobacco mosaic virus and achieved resolution down to four nanometers. (One nanometer is one billionth of a meter; a tobacco mosaic virus is 18 nanometers across.)
