Die Erfindung betrifft eine Chipkarte, wie beispielsweise die geplante Lap-on-Chip Carte, wobei die Strömung innerhalb der Mikrokanäle oder Mikrofluidikkanäle des Lab-on-Chip beobachtbar ist.The The invention relates to a smart card, such as the planned Lap-on-chip Carte, with the flow within the microchannels or microfluidic channels the lab-on-chip is observable.

So genannte Lab-On-Chip Technologien gewinnen zunehmend an Bedeutung für die medizinische Diagnostik und andere Untersuchungen. Mit dieser Technologie lassen sich mit sehr geringen Mengen an Ausgangssubstanzen und Reagenzien (Piko- bis Milliliter) vollautomatisierte und integrierte Analysen auf einem einzigen Chip realisieren. Flüssigkeiten lassen sich gezielt durch Ausnutzung der Kapillarkraft sowie durch die Kontrolle der Benetzungseigenschaften der Chipoberfläche bewegen. Die anwendungsspezifischen biologischen, chemischen und physikalischen Prozesse finden in Reaktionskammern (Kavitäten) statt, die über Mikrokanäle definiert befüllt werden.So These lab-on-chip technologies are becoming increasingly important for the medical diagnostics and other examinations. With this technology can be treated with very small amounts of starting substances and reagents (pico to milliliters) fully automated and integrated analyzes realize a single chip. Liquids can be targeted by exploiting the capillary force and by controlling the Move wetting properties of the chip surface. The application-specific biological, chemical and physical processes take place in reaction chambers (Cavities) instead, over Defined microchannels filled become.

Auf einem Glassubstrat von einigen cm2 Größe befinden sich kleine Flüssigkeitskanäle mit einer Breite von 10 µm bis etwa 200 µm und einer Höhe von 10–800 µm. Durch diese kleinen Kanäle wird die Fluidik in die Reaktionskammern (einige mm2 groß) transportiert. In der Anwendung als Zellchip werden einige Zellen in die Reaktionskammer transportiert.On a glass substrate of a few cm 2 size are small liquid channels with a width of 10 microns to about 200 microns and a height of 10-800 microns. Through these small channels, the fluid is transported into the reaction chambers (a few mm 2 large). When used as a cell chip, some cells are transported into the reaction chamber.

Bisher werden die Befüllungen der Kavitäten durch externe Mikroskop-Kamerasysteme überprüft. Diese Systeme sind groß und teuer.So far become the fillings the cavities through external microscope camera systems checked. These Systems are big and expensive.

Aufgabe der vorliegenden Erfindung ist es deshalb, eine Vorrichtung zur Beobachtung der Strömungen in Mikrofluidiksystemen zur Verfügung zu stellen, die als one-way-product mit der Chipkarte hergestellt werden kann.task It is therefore an object of the present invention to provide a device for Observation of the currents in microfluidic systems to make that produced as a one-way product with the smart card can be.

Lösung der Aufgabe und Gegenstand der Erfindung ist daher eine Chipkarte mit zumindest einem Mikrofluidikkanal zur Befüllung einer Kavität, wobei auf der Unterseite des Mikrofluidikkanals eine zumindest semitransparente Elektrodenschicht, darauf eine organisch basierte optisch aktive Schicht und darüber schließlich eine Gegenelektrodenschicht so angeordnet wird, dass der Photodetektor eine von oben in den Mikrofluidikkanal fallende Strahlung detektiert.Solution of Object and subject of the invention is therefore a smart card with at least one microfluidic channel for filling a cavity, wherein on the bottom of the microfluidic channel an at least semitransparent Electrode layer, then an organic based optically active Layer and above after all a counter electrode layer is arranged so that the photodetector detects a falling from above into the microfluidic channel radiation.

Nach einer vorteilhaften Ausführungsform umfasst der Aufbau des Photodetektors zusätzlich noch eine Lochleitschicht zwischen der transparenten Elektrode und der optisch aktiven Schicht.To an advantageous embodiment the structure of the photodetector additionally a Lochleitschicht between the transparent electrode and the optically active layer.

Soll ein Bild mit dem Flachbilddetektor durch den Mikrofluidikkanal hindurch aufgenommen werden, so durchdringt die dem Bild zugeordnete Lichtverteilung die der Lichtverteilung zugewandte Elektrode, die daher aus einem zumindest semitransparentem Material gefertigt ist. Des Weiteren wandelt die Halbleiterschicht in Verbindung mit den beiden Elektroden die Lichtverteilung in elektrische Signale um, die an den einzelnen Teilelektroden der strukturierten Elektrode anliegen.Should a picture with the flat panel detector through the microfluidic channel are received, so penetrates the light distribution associated with the image the light distribution electrode facing, therefore, from a made at least semi-transparent material.

In dieser Halbleiterschicht befindet sich beispielsweise ein Elend aus den beiden Komponenten P3HT (Absorber-, Elektronen donator und Lochtransportkomponente) und PCBM (Elektronenakzeptor und -transportkomponente), die als Bulk-Heterojunction wirkt, das heißt die Trennung der Ladungsträger erfolgt an den Grenzflächen der beiden Materialien, die sich innerhalb des gesamten Schichtvolumens ausbilden. Ebenso gut kann die Halbleiterschicht als eine mehrere Einzelschichten umfassende Schicht aufgebaut sein, in der Lochtransportkomponente und Elektronentransportkomponente in separaten Schichten vorliegen.In This semiconductor layer is, for example, a misery from the two components P3HT (absorber, electron donor and Hole transport component) and PCBM (electron acceptor and transport component), which acts as a bulk heterojunction, that is, the separation of the charge carriers takes place at the interfaces the two materials that form within the entire layer volume. Equally well, the semiconductor layer can be as a multiple individual layers comprehensive layer be constructed in the hole transport component and electron transport component in separate layers.

Bei der Herstellung des Photodetektors nach der Erfindung wird beispielsweise wie folgt vorgegangen: Auf eine zumindest semitransparente Bottomelektrode (z. B. ITO) wird eine Blendschicht aufgeschleudert. Dazu werden die Blendkomponenten in einem geeigneten Lösungsmittel (z. B. Chloroform oder Xylol) gelöst. Auf die Blendschicht wird eine semitransparente Topelektrode (z. B. ein dünnes Schichtsysteme aus Ca und Ag) aufgebracht (z.

Beispielsweise kann die organische Halbleiterschicht auch durch sein coating, Rakeln oder Siebdrucken aufgebracht werden. Außerdem weisen organische Photodetektoren eine relativ hohe Kompatibilität zu verschiedenen elektronischen Ansteuerungstechnologien auf.Organic-based photodetectors can be produced relatively simply by applying the organic semiconductor layer from the solution by means of printing technology. For example, the organic semiconductor layer can also be applied by coating, knife coating or screen printing.

Elektron/Loch blockierende Schichten sind aus der Technologie für organische LEDs bekannt. Ein geeignetes organisches Material für die Elektron blockierende Schicht ist zum Beispiel TFB.One organic photodetector can be used in addition to the photoactive layer, For example, P3HT / PCBM, CuPc / PTCBI, ZNPC / C60, conjugated polymer components or fullerene components, an electron / hole blocking layer, called auxiliary layers, include.
