New NANO MRI – By IBM

Hey, now you can see the virus on the door knob!

IBM Research 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.

Very cool tech coming to keep us healthy.

“This technology stands to revolutionize the way we look at viruses, bacteria, proteins, and other biological elements,” said IBM Fellow Mark Dean, vice president of strategy and operations for IBM Research.

This advancement was enabled by a technique called magnetic resonance force microscopy (MRFM), which relies on detecting ultrasmall magnetic forces. In addition to its high resolution, the imaging technique has the further advantages that it is chemically specific, can “see” below surfaces and, unlike electron microscopy, is non-destructive to sensitive biological materials.

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.)
