On p. 2759 Lane Baker and co‐workers from Indiana University and Oak Ridge National Laboratory describe electromagnetic micropores for the control of ion transport. Current passed through a single‐turn microcoil focuses a magnetic field gradient, creating a trap at a micropore in the center of the coil. Magnetic fluids trapped in the electromagnetic trap can be used to gate the flux of ions through the micropore, in a manner reminiscent of biological ion channels. Further applications in nano‐/microscale transport and sensor development are evident.
