A method is provided for enhancing the transport of a selected ion having a predetermined charge-to-mass ratio through a biomolecular membrane located in a space subjected to a local magnetic field. The space defines at least one reference path passing through the membrane in opposite first and second directions. The method includes the steps of creating a magnetic field which, when combined with the local magnetic field, produces a magnetic field having a flux density with at least one component representable by a component vector having a direction extending in the first direction along the path. This component of the magnetic field has a magnitude that fluctuates at a predetermined rate to produce a nonzero average value. A predetermined relationship between the ratio of the selected rate to the nonzero average value and the charge-to-mass ratio of the predetermined ion is thereby created. The predetermined relationship, is a function of the cyclotron resonance frequency of the ion. The present invention also provides an apparatus for enhancing the transport of a selected ion having a predetermined charge-to-mass ratio through a biomolecular membrane. The apparatus includes field creating means responsive to signals for creating a magnetic field which, when combined with the local magnetic field, produces a magnetic field having a flux density with at least one component representable by a component vector having a direction extending along a path through the membrane and having a magnitude that fluctuates at a predetermined rate to create a nonzero average value. The ratio of the predetermined rate to the nonzero average value has a predetermined relationship with respect to the charge-to-mass ratio of the predetermined ion which is a function of the cyclotron resonance frequency of the ion. Signal generating means is provided for generating the signals, at least some of which are generated at the predetermined rate.
An apparatus for regulating the transfer of a predetermined ion having a predetermined charge-to-mass ratio through a membrane located in a space subjected to a local static field, the space defining at least one reference path passing through the membrane, the reference path extending in a first direction and also extending in a second direction opposite the first direction, said apparatus comprising:
