navigation, search  Magnetic resonance force microscopy (MRFM)
is an imaging technique that acquires magnetic resonance images
(MRI) at nanometer scales, and possibly at atomic scales in the
future. MRFM is potentially able to observe protein structures
which cannot be seen using X-ray crystallography and protein
nuclear magnetic resonance spectroscopy. Detection of the
magnetic spin of a single electron has been demonstrated using
this technique. The sensitivity of a current MRFM microscope is
10 billion times better than a medical MRI used in hospitals.
Basic principle[edit]  The MRFM concept combines the ideas of
magnetic resonance imaging (MRI) and atomic force microscopy
(AFM). Conventional MRI employs an inductive coil as an antenna
to sense resonant nuclear or electronic spins in a magnetic
field gradient. MRFM uses a cant
