Definitions

  • the present invention relates to a flat body in the manner of a chip card for the biochemical analysis of substances according to the preamble of claim 1.
  • the flat body has at least two microfluidic devices and at least one sensor chip.
  • the at least one sensor chip is integrated in the flat body and is in direct contact with at least one first microfluidic device.
  • a flat body for biochemical analysis of substances such as DNA and proteins known.
  • This flat body has the shape of a chip card, which is designed analogously to a credit card.
  • the flat body includes a semiconductor chip having a sensor array and integrated circuits, the semiconductor chip being potted in a flat plastic material and being electrically connected to electrical contacts for reading the chip through an external readout unit.
  • On a front side of the flat body are formed as recesses in the plastic microfluidic device such as reaction chambers and channels. The front side is covered with a film and the microfluidic devices are so fluid-tight with respect to the environment, that is tightly sealed against liquids and / or gases.
  • the film of the chip card is pierced via a pointed needle analogous to a syringe tip, and the liquid is injected into a microfluidic device of the chip card.
  • the liquid comes into contact with sensors of the sensor array on the chip and constituents of the liquid can be detected directly or indirectly. Detection may be optical or electrochemical. Substances which are necessary for chemical reactions to detect the constituents of the liquid can already be located on or in the chip card or can likewise be injected into this via a pointed needle.
  • the absorption capacity of microfluidic devices on a chip card for receiving liquid is usually very low and is often limited to only a few milliliters, or to microliters or in extreme cases only to nanoliters.
  • Another problem with supplying liquid to or into the chip card via pointed needles may be the introduction of contaminants.
  • the slightest chemical or biochemical impurities can lead to errors in the quantitative and / or qualitative detection.
  • any additional device e.g. a needle with which the liquid to be examined is brought into contact increases the probability of contamination.
  • An increased effort, which is cost and time consuming, must be provided to ensure the detection quality, e.g. by thorough cleaning of all devices.
  • the device comprises a reaction chamber and a flat body.
  • the sample is amplified within the reaction chamber using reagents. Subsequently, the amplified sample is transferred to the flat body, wherein the flat body has an optical detection device for detecting the nucleic acids.
  • the WO 2009/115608 A2 relates to a cartridge system for sample preparation and sample analysis, wherein the cartridge system comprises a flat body and a sample container.
  • the sample container can be inserted linearly into the flat body so that a fluid transfer of the sample from the sample container to the flat body takes place.

Integral means that the second microfluidic device and the remaining flat body are made of at least one material together and form a coherent body, without the second microfluidic device is attached to the flat body, clamped or otherwise repeatedly attached separable and fastened.
  • the advantage of a flat body with integrated pipette lies in the possibility of large quantities of liquid between a vessel, as e.g. represents an e-cup, and the flat body easy and fast exchange. Since the flat body and the pipette integrated therein can be made of one material together, both have the same chemical and biochemical purity levels. An entrainment of impurities by additional parts in the flat body is thus prevented.
