Abstract

For processing of substances in the reservoir (3) of a microdroplet dosing device (1), movement of a solid carrier material with a binding-active surface takes place in the reservoir, and binding of the substance takes place on the surface of the carrier material which comprises magnetic particles (7) or a carrier pad.
