    专利说明:

    The present invention relates to an optochemical sensor comprising a supported polymer matrix doped with a luminescent dye whose emissivity, upon excitation with electromagnetic radiation, is to be detected by substances to be detected, such as gaseous or dissolved O 2, SO 2, H 2 O 2, CO 2 , Nitrogen oxides, halogenated hydrocarbons is changeable and which forms a sensor layer, which is covered with a transparent to the analyte, optical protection, support and / or insulating layer.
    Sensors for measuring the concentration of certain substances, such as gases in solutions or solids work either electrochemically, in which case they have the disadvantage that they consume for a quantitative detection of the gas to be determined part of the substance to be determined, whereby the measurement result is falsified or but recently opto-chemical sensors have been developed, which are characterized in that they do not change the composition of the analyte over time, but that they are the quantitative detection of the concentration of the substance to be determined or the gas to be determined only by a luminescence quenching of the contained in the sensor luminescent substance. In this case, characteristic parameters, such as the luminescence intensity, the phase shift of the luminescence signal or the decay time of the luminescence are checked, and by comparing the luminescence signal with a calibration function, a quantitative detection of the substance to be measured succeeds.
    Early opto-chemical sensors, as described, for example, in EP-A 0 550 424 or in EP-A 0 601 816, use special polymers in which gases, such as, for example, oxygen and CO 2, are readily soluble in order to control the solubility the gases in the polymer to arrive at a quantitative detection of the gases. A disadvantage of these known sensors is that they are not reusable and that they are not sterilizable due to the polymers used in these sensors, especially when using elevated temperatures and thus can be used poorly or not at all in biological material.
    From EP-B 1 114 309 a reusable, opto-chemical sensor is already known, in which a luminescent dye contained in a polymer matrix is excited to electromagnetic radiation whose emissivity changes after the excitation, whereby a quantitative measurement is possible. The polymers used in this opto-chemical sensor or the polymer matrix is formed from at least one polymer without the addition of plasticizers, wherein the selected polymer has a glass transition temperature of about 140 ° C, which is why the sensor both sterilizable and replaceable on biological material and is reusable. A disadvantage of this known, opto-chemical sensor is that a relatively large amount of luminescent ft "······························" ; «· · · · · · · · · · · · · · · · · ······························································································································································································································ and that the sensor is extremely sensitive to mechanical influences and thus usually after a few measurements so damaged that it no longer seems suitable for further use.
    The present invention now aims to provide an opto-chemical sensor in which the tendency for aggregation or migration of the luminescent Farbestoffs is greatly reduced and with which stable reproducible results can be obtained even with a multiple reuse. Furthermore, the invention aims to prevent by a special structure of the sensor attenuation of the measurement signal, even after a variety of measurements.
    To achieve this object, the opto-chemical sensor according to the present invention is characterized in that the sensor layer is formed of a layer having a plurality of separate sensor elements, which sensor elements are covered by a non-doped polymer matrix chemically corresponding to the polymer matrix of the sensor layer. The fact that the sensor layer is formed from a layer in which a plurality of separate sensor elements is included, it is possible to embed the sensor elements as far as possible in the sensor layer, so that the bleeding of the luminescent even with a multiple use and sterilization of the Sensors is prevented as much as possible and at the same time the amount of luminescent dye used can be minimized as much as possible. In addition, since the sensor elements are covered by a non-doped polymer matrix chemically corresponding to the polymer matrix of the sensor elements, it is additionally possible to form a protective layer over the sensitive sensor elements so that the number of cycles of use of the sensor element is further increased due to the protection of the measuring layer from damage or destruction At the same time, a weakening of the measuring signals due to leached or chemically changed luminescent dye is certainly avoided.
    Furthermore, by separating the sensor elements from one another, it is possible to form regions between the individual sensor elements, in which direct contact of a cover layer with the carrier is achieved, through which direct contact, in particular the mechanical stability of the sensor, is significantly increased compared to conventional products.
    In order to surround the sensitive sensor elements as far as possible on all sides and thus to ensure reproducible measurements, the optochemical sensor according to the invention is further developed such that a further layer corresponding to the non-doped polymer matrix is provided between the carrier and the layer comprising the sensor elements. By embedding the sensitive sensor layer or the sensitive luminescent dyes in a polymer matrix or polymer layer on the one hand, it is ensured on the one hand that by the specific choice of the polymer permeable to the substance to be analyzed, I Φ Φ · Λ Φ · Φ Φ · # φ φ · ΦφΟ "* φ φ φφφφ φ · φ" φ φ φ φφ φφ φ * ♦ * · φ · φφ φφφφ which forms the polymer matrix, enables a safe and reliable measurement of the substances to be analyzed and at the same time ensures that a Bleeding or washing out or inactivating the sensitive luminescent dyes is certainly withheld even with a plurality of measurements or repeated measurements. Finally, migration of the luminescent dyes into surrounding layers is prevented. Such prevention of migration into surrounding layers is of particular importance because the luminescent dye would be present in a physically and chemically different environment and would behave differently with respect to the analyte sensitivity and thus lead to a falsification of the measurement, for example by formation of a " alien "population of dye molecules, would lead.
    It has also been found that at the interface between the matrix polymer forming the polymer matrix and other materials chemically different from the matrix polymer, it is preferred to aggregate the dye molecules and thus form a " alien " Population of colorant molecules or to self-erase, i. there could be no sensitivity to the analytes to be measured. In addition, in the case of such an aggregate formation, the behavior of the sensor with the known characteristic function of the Stem-Volmer-Falselight model could only insufficiently described and a numerical curve fitting of calibration points can be achieved only with unnecessarily large residual deviations. On the other hand, the design according to the invention makes it possible to avoid the transfer of dye molecules into a "disturbing" population, and thus it is possible to describe the characteristic curve exactly using the Stern-Volmer-Falselight equation.
    In order to further increase the number of cycles of recycling the opto-chemical sensor according to the invention, the sensor according to the invention is further developed such that the two layers of non-doped polymer matrix in the region surrounding the sensor elements are chemically and / or physically connected to one another. Due to the chemical and / or physical connection of the two layers of non-doped polymer matrix, the sensor elements are completely and in particular tightly surrounded by the non-doped polymer matrix, so that a decrease in activity due to unintentional leaching or bleeding of the luminescent dye is certainly lagged behind and thus the cycle number of the sensor can be further increased.
    Furthermore, as corresponds to a development of the invention, the opto-chemical sensor is designed so that the plurality of sensor elements is designed as a field of mutually evenly spaced sensor elements, in particular punctiform sensor elements. Since the opto-chemical sensor is formed by arranging a plurality of sensor elements as a field of mutually uniformly spaced sensor elements, on the one hand the amount of luminescent dye used can be minimized while, on the other hand, a large sensor or measuring device can be used. «·« 4 ·· Λ 4 • · · Μ «· • ·

    Surface can be provided with which quantitative and reproducible measurement results can be achieved with certainty.
    According to one development of the invention, the opto-chemical sensor is characterized in that the array of sensor elements is formed from at least two groups of sensor elements which are different from one another with respect to the amount or type of doping with luminescent dye. By the field of sensor elements from at least two mutually different groups of sensor elements is formed, wherein the groups are different from each other by the type of doping with luminescent dye or the type of matrix polymer, it is possible to simultaneously a plurality of substances to be detected, such as gaseous or dissolved oxygen , S02, H202, C02, nitrogen oxides, halogenated hydrocarbons, and the like, with one and the same sensor to detect quantitatively. Due to differences in the nature of the matrix polymer or else the type of luminescent dye, differently intense signals are simultaneously obtained for one and the same substance to be detected, so that, for example, one and the same sensor can be used to quantitatively determine a wide range of concentrations of the dissolved substances.
    By, as is known per se, the opto-chemical sensor by a support protective and / or insulating layer of coarse or fine-pored polytetrafluoroethylene or nylon membranes, in particular with a pore size between 0.1 pm and 160 pm, preferably 01 pm and 30 pm, carbon fiber fabrics, special textile fiber fabrics, semipermeable membranes of soluble polymers, in particular soluble, perfluorinated polymers, or a combination thereof, is covered, it is further possible to provide mechanical and chemical protection of the sensor surface. By forming a porous or semipermeable layer, however, the passage of the substance to be analyzed to the sensor surface is not hindered and ensures rapid adjustment of the measured value. Furthermore, it is possible with such an insulating or protective layer to shield the sensor against environmental influences or ambient light. For a dense material composite and in particular to further increase the service life of the opto-chemical sensor and thus the number of use cycles, the sensor according to the invention is further developed in that the support, protective and / or insulating layer at least partially in the embedded, the non-doped polymer matrix having sensor elements, which in particular destruction of the polymer matrix is obstructed.
    In order in particular to withstand unintentional excitation by extraneous light or by chemical foreign substances of the luminescent dye contained in the sensor elements, the sensor according to the invention is further developed such that a cover layer is provided over the non-doped polymer matrix or the optical support, protective and / or insulating layer , which is formed according to a preferred embodiment of two outer layers and that between the outer layers of the support, protection * * · ··· »« ··· »* * C 9 · *« C - · I »· · · · I It is also possible to arrange an insulating layer. The pigmentation of the cover layer with soot makes it possible, in particular during a measurement or during a plurality of successive successive measurements, to prevent the unintentional excitation with extraneous light and thus falsification of the measurement signal. Particular preferred properties, and in particular both mechanical support, protection against chemical attack and optical isolation can preferably be achieved if, as in a further development of the invention, the top layer of silicones, partially fluorinated silicones and perfluorosilicones, coatings of soluble polymers, especially soluble, perfluorinated polymers or a combination thereof. By forming the cover layer of two layers, it is possible to reliably and completely embed the often poor adhesion-bearing support, protective and / or insulating layer in the cover layer, whereby unintentional detachment of the insulating layer or detachment of the sensor layer from the support Security is at a standstill.
    By, as corresponds to a preferred embodiment of the invention, the outer cover layer is pigmented with carbon black and the inner cover layer is pigmented with Ti02, one hand, to achieve the best possible backscattering of the excitation and luminescence and on the other hand the unintentional excitation with extraneous light safely disregard injury.
    In order to ensure that only the side of the sensor having a support, protective and / or insulating layer comes into contact with the measurement medium and, furthermore, to prevent damage to the sensor during handling, the sensor is preferably developed in such a way that the sensor is in one Mounting cap is held, which is preferably provided with clamping or holding elements, which hold the sensor in such a way that it can not accidentally fall out of the mounting cap on the one hand and on the other hand can be replaced at any time if required. In this case, the penetration of the measuring medium or the cleaning media between the carrier or the substrate and the sensor layer and thus the detachment of the sensor from the carrier is prevented in particular. For proper operation of the opto-chemical sensor, the mounting cap is further configured to be provided with a light guide defining member which forms the connection between the sensor and the measuring electronics.
    A particularly durable and frequently recyclable sensor can be obtained according to the present invention in that at least the polymer matrix of the sensor layer of soluble, amorphous, perflourierten polymers, such as polymers of substituted perfluoro-2-methylene-1,3-dioxolanes or perfluoro ( 4-vinyloxy-1-butene), but especially from poly [2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole-co-tetrafluoroethylene] is formed.

    5 shows a section through the opto-chemical sensor according to the invention in a holding element.
    In Fig. 1 with 1 denotes an opto-chemical sensor whose sensor layer is formed of a plurality of sensor elements 2. The sensor elements 2, which are formed in the illustration of FIG. 1 as punctiform sensor elements 2, which have a uniform distance a between them, are embedded in a polymer matrix 3, which polymer matrix 3 is formed from the same polymer material, as the sensor elements 2, however, the sensor elements 2 are additionally doped with a luminescent dye.
    In connection with FIG. 1, it is unnecessary to state that the sensor elements 2 of the opto-chemical sensor 1 can have any other shape in addition to the illustrated circular shape, such as elliptical, angular or the like, and both the distance a between the sensor elements 2 and the number thereof in the opto-chemical sensor 1 can vary as desired.
    Finally, the sensor elements 2 can also be doped with different or different luminescent color materials or be formed from different matrix materials in order to simultaneously enable either different intensities of the measurement signal or to be able to detect a plurality of gaseous or dissolved substances in a sample.
    In Fig. 2, which shows a section through the opto-chemical sensor 1 according to Fig. 1, it can be seen that the polymer matrix 3 is applied to a support 4, which carrier 4, for example, from an optically inactive, translucent material, such as opposite Acids, bases and organic solvents insoluble or resistant polymers, such as PET, polycarbonate, polymethacrylates or glass is formed. On the support 4, in the illustration according to FIG. 2, a base layer 5 consisting of the material, such as the layer 3, is applied, which polymer material is not doped with a luminescent dye. The base layer 5 is in this case formed either as a continuous layer on the support 4 or in the form of island elements distributed on the support 4 layer elements which slightly overhang the sensor elements 2 on all sides, as shown in Fig. 3. On the layer or base layer 5, the sensor elements 2 are applied uniformly spaced apart from each other and the sensor elements 2 are in turn covered with the polymer matrix 3, in which no luminescent dye is integrated. The layer 3 is in this case designed in such a way as • t 99 9999 9999 9 · »♦ 9 9 · ♦ 7 9« 9 9 9 9 9 9 9 9 * «r '99 9 • 9 9 9 99 9 9 9999 99 9 9» 9 99 999 9 999 9999 that it is in each case between the sensor elements 2 in direct contact with the base layer 5 and is chemically and / or physically connected to this base layer 5 in the region 6 between the sensor elements 2. By such a design it is possible on the one hand, the To completely cover sensor elements 2 and thus to prevent bleeding of the sensor elements 2, in particular of the luminescent dye contained in the sensor elements 2 with certainty and on the other hand to make each sensor element 2 independent of the other sensor elements 2 measuring devices. Furthermore, it is possible by the arrangement of the polymer matrix on the sensor to protect the sensor itself against chemical attack, since in a frequent field of use of opto-chemical sensors, namely the monitoring of food processes, it is useful or important, the polymer matrix previous disinfection media, such as peroxyacetic acid, phosphoric acid, nitric acid, hydrochloric acid, caustic soda or hypochlorite to protect. Furthermore, by arranging the polymer matrix, for example, oxidation of the sensor dye is certainly withheld.
    However, the embodiment according to FIG. 2 can also be designed such that the sensor elements 2 are in direct contact with the carrier 4, in which case the polymer matrix or layer 3 between the sensor elements 2 is in direct contact with the carrier 4 with it physically and / or is chemically connected, in turn, to prevent inadvertent leakage or leaching of Lumineszenzfarbestoff from the sensor elements 2.
    In the illustration according to FIG. 4, in which the reference symbols of the preceding figures have been retained as far as possible, a base layer 5 is again applied to the carrier 4 and the sensor elements 2 are embedded in the polymer matrix 3. In order to give the sensor 1 according to FIG. 3, on the one hand, greater strength and, on the other hand, to withhold accidentally damaging both the polymer matrix 3 and the sensor elements 2, a schematically illustrated supporting, protective and / or insulating layer 7 is provided on the polymer matrix 3 For example, applied from coarse or fine-pored polytetrafluoroethylene. Finally, a cover layer 8 is applied above and below the insulating or support layer 7. The cover layer 8 is in this case formed either from a polymer pigmented with soot, in order to prevent an unintentional excitation of the sensor with extraneous light.
    In a construction of the sensor 1 according to FIG. 4, regions 6a of the carrier 4 remain free at regular intervals and there is a direct physical or chemical connection of the covering layer 8 with carrier 4 in these regions 6a. By a direct connection, the mechanical stability of the sensor or its layer structure is significantly increased and in particular reduces the tendency of the sensor for delamination. For a particularly good hold of the support, protective and / or insulating layer 7 on the sensor, the cover layer 8 according to a variant of the invention is formed so that it is in two parts, wherein that part of the cover layer 8, which is directed to the sensor, the cover
    Layer 8a is formed with Ti02 pigmented, on the cover layer 8a, the protective or insulating layer is disposed and over the support, protective and / or insulating layer, the second part of the cover layer, namely the cover layer 8b is arranged, which from the same base material as the top layer 8a is made, but instead is pigmented with carbon black. Such a design on the one hand achieves excellent backscattering of the excitation and luminescent light by the TiO 2, whereby, for example, the amount of fluorescent dye used can be reduced and, on the other hand, good soot isolation by the carbon black. By, for example, embedding the layer 7 in the layer 8, a mechanically integral and stable composite material is achieved.
    In order to be able to carry out a particularly efficient measurement with the opto-chemical sensor 1 according to the invention, the base layer 5 and / or the polymer matrix 3 is furthermore designed such that it is pigmented, for example with TiO 2, in order to achieve the best possible light scattering to reach. Finally, the sensor elements 2, which are embedded in the polymer matrix or are arranged on the base layer 5, may be different from one another in that they are doped with, for example, two different luminescent dyes in order to be able to measure different substances to be detected simultaneously. For a practical use of the sensor 1 according to the invention, the sensor 1 is held in a mounting cap 9, as shown in Fig. 5. The mounting cap 9 in this case has, on the one hand, a clamping device 10 for holding the sensor 1, wherein the sensor 1 is clamped in the mounting bracket 10 with its end regions 11, which end regions are free of sensor elements 2 doped with luminescent dye. By firmly holding the sensor 1 by means of the clamping devices 10, an unintentional detachment of the layers applied to the carrier 4, such as the base layer 5, the protective layer 7 and the cover layer 8, is moreover avoided with certainty.
    On the rear side of the opto-chemical sensor 1, a schematically illustrated fixing element 12 can be seen, into which fixing element 12 an optical waveguide 13 is inserted for connecting the opto-chemical sensor 1 to an optoelectronics or measuring electronics, not shown. In this case, the light guide 13 can be formed, for example, from a glass fiber, a glass fiber bundle or a glass rod designed as a light guide, or other devices suitable for light conduction.
    In summary, it should be noted that due to the island-like arrangement of the sensor elements 2 in the polymer matrix 3 and in the layer 3 on the one hand bleeding of the sensor elements 2 and thus a deterioration of the sensor 1 can be withheld safely even with a plurality of inserts. At the same time, such an arrangement makes it possible to provide a cost-effective and efficiently measuring sensor 1 with which different gaseous or dissolved substances to be detected can also be measured with one another.
