IBM microscope 100 million times stronger than MRI

by Daniel Terdiman

According to IBM Research: 'An ultrasensitive silicon cantilever detects the tiny magnetic force between a nanoscale magnetic tip--green--and the hydrogen nuclei present in the virus particles placed at the end of the cantilever--blue, seen in the reflection. Nanoscale magnetic resonance imaging is achieved by manipulating the hydrogen nuclei in the sample with a radiofrequency magnetic field generated by a 'microwire'--red.''

IBM Research has built a new nanoscale microscope capable of creating images with 100 million times finer resolution than existing MRI technology.

The breakthrough, announced Monday, was made possible through a process called magnetic resonance force microscopy, which, according to IBM, detects "ultra-small magnetic forces." The technique is said to be able to "see" beneath surfaces and be safe for sensitive biological materials.

IBM said that it ran a test using the new system that established for the first time, magnetic resonance imaging on nanometer-scale items. By running it on a tobacco mosaic virus that is 18 nanometers across--18 billionths of a meter--the new system achieved resolution down to 4 nanometers.

Here is a link to a YouTube video about the technology.

Anything that is 100 million time more than something is impressive. That's incredible.

So...does that mean all those expensive and highly touted fMRIs that neuro scientists claim can tell us what we are thinking....are those scans 100 million times less accurate?

Okay, now THIS is cool technology news. :)

I do wonder as they keep getting smaller and smaller, when the Heisenberg uncertainty principle starts to take effect. Is the method / act of observing changing the results?
