Researchers at the University of Illinois at Urbana-Champaign have succeeded in generating intense magnetic fields on the nanoscale by focusing electric current through a nanosized metal constriction. The feat has allowed them to perform magnetic resonance imaging (MRI) and spectroscopy at spatial resolutions of just 10 nm using well established nuclear magnetic resonance (NMR) techniques such as “Fourier-transform”. Such nanoscale MRI could come in extremely useful for imaging biological organisms and, if improved, the new technique might even be used to image viruses and protein macromolecules in the future…….
