  Article:   MD SIMULATIONS OF BIOLOGICAL ION CHANNELS IN INTENSE MAGNETIC FIELDS.

  Abstract:  The transport of sodium ions through a model membrane channel in the presence of intense static magnetic fields is investigated by nonequilibrium molecular dynamics. The effect of the magnetic fields (1 - 100 T) appears to be exerted not mainly on the transiting ions (presumably reducing their transport rates by deflections), but rather on the water molecules, favoring statistically their polarization during the ion passages and leading indirectly to a slight increase of the ion current
