Definitions
- the invention relates to a method for moving small quantities of liquid in microchannels and to a microchannel system for carrying out the method.
- Miniaturized fluidic systems often consist of closed channels which can be produced from plastics, semiconductor materials or from glass. Such closed channels are z. In M.G. Pollack and R.B. Fair, Applied Physics Letters, 2000, 77, 1725-1728.
- Manufacturing processes are z. As wet-chemical etching or hot embossing of plastics to produce the channels in the substrates. Subsequently, the substrates structured in this way are sealed with a cover. Typical channel dimensions are diameters in the range between 50 ⁇ m and a few mm and a length of the entire system of a few cm. For lab-on-the-chip applications in these channels z. B. biochemical reactions are carried out. For this purpose, generally dosing devices, mixers, reaction chambers and branches in such a system would have to be realized. To move the liquid pump-like systems are necessary.
- peristaltic pumps US Pat. No. 6,408,878,
- electrokinetic pumps US Pat. No. 6,394,759
- centrifugal force US Pat. No. 5,472,603
- Electrokinetic pumps require z. However, for example, voltages of several 100 V, so are less suitable for portable devices. In the so-called lab-CDs, the liquids can only be moved in one direction, namely outwards. Miniaturized peristaltic pumps are very expensive and therefore expensive.
- a hydrophilic channel can be filled with a solution, but with a filled channel, no further movement or flow is possible, which would be mediated by the capillary force.
- the object of the present invention is to provide a method and a system with which small quantities of liquid in microchannel systems can be moved in an easily controllable and programmable manner.
- the procedure should be easy to carry out and the necessary agile materials can be small, robust and light, so that the process can also be realized with portable chip laboratories.
- a quantity of liquid is introduced into a channel system which comprises at least one region which corresponds topologically to a ring, so that a closed path of the liquid is possible.
- acoustic waves are radiated into the liquid, which have at least one asymmetric component in the plane of the channel system, which defines the direction of movement of the liquid.
- a flow is generated in the liquid (“acoustic streaming") .Swing to the movement of the liquid in a closed path, only low powers are necessary, since there is no large volume on the closed path As a result of the asymmetrical component, the liquid is imparted with a direction of movement which it can move along the closed path.
- the channel system may have different geometries as long as a topologically annular region is included which serves for the directional movement of the liquid on a closed path.
- a topologically annular region is included which serves for the directional movement of the liquid on a closed path.
- Especially simple is the use of a simple ring without branches.
- the channel system is open at the top, z. B. as a groove in a substrate.
- a channel system Insensitive to external influences is a channel system that is enclosed on all sides. The filling of such a channel system takes place entwe ⁇ before a lid is applied to the channel-shaped channel system or through a corresponding filling opening to the z. B. an eyedropper can be set. At another point of the channel system, a vent opening is provided, so that the air displaced by the introduced liquid can escape. Since the movement in the channel system is mediated by the sound-induced flow, a tight shut-off is not necessary, as is the case with other prior art methods which use hydrostatic pressure for movement.
- Vor ⁇ geous is the use of a material that is penetrated by acoustic waves, for example, glass, non-elastic plastic or semiconductor materials. In this way it is ensured even when externally arranged sound generator, that the movement is mediated by the generated with the sound waves "acoustic streaming" and not by a sound wave induced movement of the substrate material itself.
- the sound waves can be generated with different devices, for. B. with piezoelectric volume oscillators, the outside of the sound waves
- interdigital transducers as they are known from high-frequency filter technology.
- Such interdigital transducers which are applied to piezoelectric materials, can be generated by applying a frequency of 1 to a few 100 MHz for excitation of acoustic waves, in particular surface acoustic waves, are used in the piezoelectric material.
- the sound waves thus generated can be coupled into the system, as described in DE 103 25 313 B3 for the case of film-shaped capillary columns.
- the interdigital transducer is brought into direct contact with the liquid, ie it is part of the microchannel system.
- the sound wave generated by the interdigital transducer is transmitted directly into the liquid.
- a further advantageous embodiment provides that the channel-like channel system is covered with a film, preferably made of plastic, against which the interdigital transducer is pressed directly in order to allow direct transmission of the sound waves into the liquid.
- the piezoelectric material usually a chip, can also be used directly as a termination of the channel system and thus represent a part of the channel system.
- a plurality of sound wave generating devices may be provided at different locations of the channel system.
- a microchannel system according to the invention for moving small amounts of liquid has at least one channel, which represents a closed path.
- a sound generating device is arranged such that a sound wave can be coupled in directionally into the channel.
- the inventive method is particularly advantageous to use when individual areas of the microchannel system are biologically, chemically, physically or otherwise functionalized.
- the liquid can be supplied by means of the method according to the invention in a microchannel system according to the invention, so that the entire liquid is safely in contact with the functionalization.
- the liquid can be guided past correspondingly arranged measuring points.
- FIG. 1 a a schematic longitudinal sectional view of a system according to the invention
- FIG. 1b is a cross-sectional view of the system of FIG.
- FIG. 2 shows a schematic longitudinal section of another embodiment according to the invention
- FIG. 3 shows a cross section of a further embodiment according to the invention.
- FIG. 4 shows a schematic longitudinal section through a further embodiment according to the invention.
- FIG. 1a shows a longitudinal section through a microchannel system. Visible is the microchannel 3, the z. B. has a diameter in the range of 50 microns to a few mm. He is z. B. formed by wet chemical etching in a substrate 1, the z. B. glass, semiconductor materials or ei ⁇ NEM non-elastic plastic. In the channel, the liquid moves, which is exemplified by the crosses 5. The direction of movement is designated by 19.
- FIG. 1b shows a cross section in the direction of view A of FIG. 1a.
- the annular channel 3 has a filling opening 7, which is visible in this cross-sectional view.
- a piezoelectric substrate 13 is arranged in the region of a corner, on which there is an interdigital transducer 11, which can be driven in a manner known per se and thus not shown here with an alternating electric field.
- a coupling medium for example water
- Interdigital transducers which are known per se from surface wave filter technology, encompass comb-like metallic electrodes whose double finger spacing defines the wavelength of the surface acoustic wave and which are determined by optical photolithography processes, for example. B. can be made in the range of 10 microns finger spacing. Such interdigital transducers are provided on piezoelectric crystals in order to excite surface acoustic waves thereon in a manner known per se. Applying an alternating electrical field of a few to a few 100 MHz in a manner known per se to the interdigitated finger electrodes of the interdigital transducer 11 causes the generation of surface acoustic waves, which are similar to those described in DE 103 25 313 B3 for the formation of Sound waves 15, 17 lead. The application of the alternating field can via corresponding electrical connections or z. B. by wireless Ein ⁇ radiation.
- the position of the interdigital transducer 11 and the emission directions of the sound waves 15, 17 are also indicated in FIG. 1a, although they would not be visible per se in the longitudinal sectional view of FIG.
- the filling hole 7 and the vent hole 9 are indicated in Figure Ia, which should actually not be visible in the longitudinal sectional view of Figure Ia, as they are provided in the embodiment shown in the upper end 18.
- the arrangement of the interdigital transducer 11 in one corner of the channel system 3 ensures that only one sound component 15 acts in the direction of the channel 3, while the other sound wave generated by the interdigital transducer is emitted to the outside.
- a unidirectional transducer design can be used that radiates in one direction only. Such a unidirectional transducer can be used at any point of the channel 3.
- geometries can be realized in which the counter-jet 17 is not emitted to the outside, but is specifically absorbed or reflected.
- the channel system may have different geometries, as long as only one closed track is possible.
- Another embodiment shows z. B. Figure 2 with a branch 4.
- the interdigital transducer 11 is used as described for Figure 1 to generate a movement in the direction 19.
- Another interdigital transducer 12 can cause a movement along the branch 4 in the direction 20.
- the direction of movement of the liquid can be reversed so that the liquid moves in the direction 22.
- the channel system is open at the top.
- FIG. 3 shows another embodiment of a microchannel system according to the invention in cross-section.
- the channel system 3 is closed by a plastic film 21, on which the piezoelectric material 13 is pressed with the interdigital transducer 11 applied thereto, so that the air gap between the transducer and the film is smaller than the sound wavelength (1 to several 100 microns) to reflections on Air gap to avoid.
- the sound wave penetrates the plastic film and the energy transfer to the liquid occurs through acoustic streaming and not through the sound-induced movement of the film itself.
- the piezoelectric material for generating the acoustic waves is used directly as a cover for the channel system.
- FIG. 4 shows, in a schematic representation, a microchannel system according to the invention with a functionalized region 23.
- B. have a physical, chemical, biological or other functionalization, which is provided for a reaction with the liquid in the channel system 3, 4.
- a flow is generated either in the channel 3 with the help of the interdigital transducer 11 or of the interdigital transducer 14 as described.
- Creation of a further Ren alternating electric field to the interdigital transducer 12 causes a movement in the direction 20 through the branch 4.
- the liquid is thus guided past the functionalized region 23.
- the z. B. can be electrical or optical. 27 also indicates only schematically the electrical connection of this measuring device. If the liquid moves in the channel 3 z. B. by exciting a flow with the Interdigi ⁇ taltransducer 11 or with the interdigital transducer 14, the liquid is guided past this measuring point 25. The continuous flow ensures that the entire liquid flows past the measuring point.
- the generation of sound waves in the liquid by means of surface acoustic waves which are generated by an interdigital transducer on a piezoelectric material is particularly advantageous for the method according to the invention, since the sound wave thus generated already constitutes a large component in the direction of the channel Has.
- the method according to the invention or the microchannel system according to the invention have the further advantage that they can be used not only for moving the liquid along the channel, but also for mixing the liquid.
- the sound wave generating devices are operated with so little power that the energy does not suffice for the flow of the entire system.
- two transducers which have an opposite direction of emission such as, for example, can be used. As the transducers 11 and 14 of Figure 2, are operated simultaneously, so that a flow of the liquid is not possible and only a natural ⁇ mixture takes place.
