Each channel has at least one valve (4), by means of which a fluid flow can take place via any of the channels adjoining the common channel section. By means of a bidirectional actuator (5) that can be regulated with regard to its pressure pulse, the fluid flow is defined in at least one channel, through which the compartment to be positioned is transported into the common channel section. A compartment positioned in the common channel section is discharged into a depot device (10) by means of a targeted pressure pulse build-up in the common channel section by means of a further integrated actuator (8). The device contains at least one detection unit for the phase boundary between the compartment and the separation medium (7a) and at least one detection unit for the compartment content (7b) as well as optionally a ...
Description
Die Erfindung betrifft eine Vorrichtung zum Positionieren und Ausschleusen von in einem Separationsmedium eingebetteten Fluidkompartimenten (Abbildung) nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for positioning and discharging of fluid compartments embedded in a separation medium (Figure) according to the preamble of claim 1.
Im Rahmen von mikrotechnischen Hochdurchsatzverfahren werden durch verschiedene Techniken große Probenzahlen mit kleinen Probenvolumina erzeugt, die in geeigneter Weise deponiert, gezielt adressiert und weiterverwendet werden sollen. Für die Deponierung der Proben werden üblicherweise Mikrotiterplatten verwendet, die mittels Pipettier-Robotik adressiert werden. Ein weiterer Ansatz besteht in der Erzeugung von Fluidkompartimenten, wobei im allgemeinen eine Probenflüssigkeit und eine mit ihr nichtmischbare Flüssigkeit oder ein Gas mittels Aktuatoren in einem geeigneten Chip auf die Weise zusammengeführt werden, dass die Probenflüssigkeit kompartimentiert wird und die erzeugten Fluidsegmente (im Folgenden als Kompartimente bezeichnet) in der anderen Flüssigkeit oder dem Gas (im Folgenden als Separationsmedium bezeichnet) eingebettet sind. Die Deponierung erfolgt dann vorzugsweise in einem angeschlossenen Schlauch oder einer Kapillare. Mit Hilfe geeigneter Chips besteht anschließend die Möglichkeit, ausgewählten oder allen Kompartimenten im Durchfluss weitere Fluide zuzudosieren.in the Frameworks of microtechnical high-throughput processes are implemented by different techniques great Sample numbers generated with small sample volumes that are appropriate Should be deposited in such a way, specifically addressed and reused. For the Samples are usually deposited Microtiter plates are used, which are addressed using pipetting robotics become. Another approach is to create fluid compartments, generally one sample liquid and one immiscible with it Liquid or a gas by means of actuators in a suitable chip in the way together be that the sample liquid is compartmentalized and the generated fluid segments (hereinafter referred to as compartments) in the other liquid or gas (hereinafter referred to as separation medium) are embedded. Landfilling is then preferably carried out in a connected hose or a capillary. With the help of suitable chips there is then the Possibility, chosen or add further fluids to all compartments in the flow.
Bei dem Kompartiment-Fluid kann es sich gegebenenfalls um Wasser oder eine wässrige Lösung handeln. Die Kompartimente können dabei gegebenenfalls Edukte für eine chemische Reaktion, Enzyme, Substrate, Cofaktoren oder einzelne, mehrere einzelne, einen Verband oder Verbände von pro- und/oder eukaryotischen Zellen oder Indikatoren, insbesondere pH-Indikatoren, oder eine Kombination der genannten Inhalte enthalten. Auch können die Kompartimente an Mikrocarrier gekoppelte einzelne, mehrere einzelne, einen Verband oder Verbände von pro- und/oder eukaryotischen Zellen enthalten. Die zudosierten Fluide können beispielsweise Reaktanden, Substrate, Gase oder Wachstumseffektoren beinhalten.at the compartment fluid may be water or an aqueous solution act. The compartments can where appropriate, educts for a chemical reaction, enzymes, substrates, cofactors or individual, several individual, an association or associations of pro- and / or eukaryotic Cells or indicators, especially pH indicators, or a Combination of the mentioned content included. They can also Compartments single, several single, coupled to microcarrier, an association or associations of pro- and / or eukaryotic cells. The metered Fluids can for example reactants, substrates, gases or growth effectors include.
Auf diese Weise können die eingebetteten Kompartimente in ihrem Depot verschiedene Schicksale, wie unterschiedliche Produktbildung oder unterschiedliches Wachstum, haben. Dies erfordert zu einem gegebenen Zeitpunkt eine gezielte Ausschleusung bestimmter Kompartimente für eine weitere Verwendung.On this way the embedded compartments in their depot different fates, such as different product formation or different growth, to have. This requires targeted at a given time Removal of certain compartments for further use.
Vorzugsweise enthalten mindestens die Depots mindestens einen zusätzlichen Marken zur Identifikation mindestens eines Kompartimentes. Der Marker besteht vorzugsweise aus mindestens einem Fluidsegment, wobei das mindestens eine Fluidsegment zu einem Detektorsignal führt, das signifikant verschieden vom Detektorsignal aller Fluidsegmente ohne Markerfunktion und signifikant verschieden vom Detektorsignal des Separationsmediums ist.Preferably at least the depots contain at least one additional one Brands to identify at least one compartment. The marker preferably consists of at least one fluid segment, the at least one fluid segment leads to a detector signal that significantly different from the detector signal of all fluid segments without Marker function and significantly different from the detector signal of the Separation medium is.
Der erfindungsgemäßen Vorrichtung kommt dabei die Aufgabe zu, das auszuschleusende Kompartiment in der entsprechenden Fluidstrecke zu positionieren und anschließend die Ausschleusung auszuführen, so dass das ausgewählte Kompartiment einer weiteren Verwendung zugeführt werden kann.The device according to the invention the task here is to remove the compartment to be discharged to position the corresponding fluid path and then the Carry out removal, see above that the selected Compartment can be used for further use.
