ABSTRACT:
The present invention is related to a method for controlled transport of magnetic beads between a position X and different position Y, such that the magnetic beads are manipulated or transported by applying successively a series of N local magnetic fields which have magnetic field gradients different from 0 in the neighborhood of said magnetic beads. Each of these N local magnetic fields is generated by a single current carrying structure, in which the current density is not constant. The invention generally relates to application in the domain of biochips and micro-arrays, used in diagnostics, genetics and molecular studies.
