Described is a fluidic microsystem (100) with at least one compartment (10) for the receiving and/or the through-flow of a liquid and having an electrode arrangement (20) with a multiplicity of electrodes (21-28), between which a coaction zone (11) is established, whereby the compartment (10) possesses at least one wall (12-14), through which electromagnetic radiation can be linked into the said coaction zone (11) in accord with a predetermined incident direction (B), and on at least one electrode (21-28) a cooling apparatus is provided, and on which at least one respective electrode (21-28) at least one reflector layer (21b, 22b, 25b, 26b, 26c, 21c) is provided, and wherein the respective electrode (21-28) is at least partially shielded in reference to the incident beam direction (B), and having at least one heat conducting layer (50) by means of which the respective electrode (21-28) stands in thermal communication with a wall of the compartment (10), and/or includes an active cooling element (21c), which is placed in thermal contact with the respective electrode (21-18).
A fluidic microsystem (100) with at least one compartment (10) for the receiving and/or the through-flow of a liquid and having an electrode arrangement (20) with at least one electrode (21-28), by which a coaction zone (11) is established, whereby the compartment (10) possesses at least one wall (12-14), through which the electromagnetic radiation can be linked into the said coaction zone (11) in accord with a predetermined incident direction (B), therein characterized, in that on the at least one electrode (21-28) a cooling apparatus (21b, 22b, 25b, 26b, 26c, 50, 21c) is provided.
A microsystem in accord with one of the foregoing claims, wherein the at least one reflector layer is produced from a metal or a metal alloy with a reflection coefficient in the infrared spectral range, which coefficient is at least as large as the infrared reflection coefficient of copper, aluminum or gold.
A microsystem in accord with one of the foregoing claims, in which the electrodes are made from a material which is transparent in the infrared spectral range.
A microsystem in accord with one of the foregoing claims, wherein, external to the compartment (10), is placed a light source with a fixed beam direction (B) adjustable relative to the coaction zone.
A procedure for the manipulation and/or the analysis of samples with electrical forces in a fluidic microsystem (11) with at least one compartment for the receiving and/or the through-flow of a liquid and having an electrode arrangement (20) with at least one electrode (21-28), by which a coaction zone (11) is established, whereby the compartment (10) possesses at least one wall (12-14), through which the electromagnetic radiation can be linked into the said coaction zone (11) in accord with a predetermined incident direction (B), therein characterized, in that on the at least one electrode (21-28) a cooling apparatus (21b, 22b, 25b, 26b, 26c, 50, 21c) is provided.
The use of a procedure or a microsystem in accord with one of the foregoing claims, for the analysis of DNA or protein, in materials research, in combinatorial chemistry, or for the identification and/or manipulation of biological cells.
