In an arrangement for the transport of at least one magnetic particle fraction through a microfluidic system including a structure with micro-channels and means for generating a back and forth flow of fluid in the channels in which the magnetic particle fraction is contained for movement of the magnetic particles through the micro channels, means are provided for generating a magnetic field to be switched on while the fluid flows in one direction for fixing the magnetic particles and to be switched off while the fluid flows in the opposite direction so that the magnetic particles are carried along with the fluid when flowing in that direction.
