Abstract: An arrangement is provided in at least one embodiment, having a magazine for supplying a plurality of microfluidic devices. The microfluidic devices each contain at least one element/device for binding at least one biological molecule, wherein the at least one element/device for binding the at least one biological molecule can be moved relative to the microfluidic device. A sample presumably containing biological molecules to be examined is introduced into the microfluidic device. The biological molecule to be examined is bound by the at least one element/device for binding the biological molecule. In at least one embodiment, the at least one element/device for binding the at least one biological molecule, or the substrate-molecule complex, can then be moved in the microfluidic device, e.g. in accordance with a predetermined reaction sequence, for example by means of a magnetic field. The microfluidic device is transported through the arrangement.
