Abstract

Described is a fluidic microsystem with at least one compartment for the receiving and/or the through-flow of a liquid and having an electrode arrangement with a multiplicity of electrodes, between which a coaction zone is established, whereby the compartment possesses at least one wall, through which electromagnetic radiation can be linked into the said coaction zone in accord with a predetermined incident direction, and on at least one electrode a cooling apparatus is provided, and on which at least one respective electrode at least one reflector layer is provided, and wherein the respective electrode is at least partially shielded in reference to the incident beam direction, and having at least one heat conducting layer by means of which the respective electrode stands in thermal communication with a wall of the compartment, and/or includes an active cooling element, which is placed in thermal contact with the respective electrode.
