Direct imaging technology reaches the nanoscale

Abstract:
Magnetic resonance imaging (MRI) is a powerful imaging technology that serves as a non-invasive method to render images of the inside of an object. It is primarily used in medical imaging to demonstrate pathological or other physiological alterations of living tissues. MRI also has uses outside of the medical field, for instance as a non-destructive testing method to characterize the quality of products such as produce and timber. Conventional MRI usually operates at the scale of millimeters to micrometers - 3 micrometers at best - which is good enough for the mostly medical diagnostic purposes it is used for. Researchers have now shown that the imaging of nuclear spins using magnetic resonance, the basis for MRI, can be pushed to sub-100nm resolution into the nanoscale realm. They demonstrated that using an emerging technique based on force detection, they can image nuclear spins with a sensitivity that is 60,000 times better than MRI. The resolution is about 30 times better than the most advanced conventional MRI imaging. By improving this technique, researchers will be able to push deeper into the nanometer regime and approach the capability needed for direct three-dimensional imaging of individual macromolecules.
