Definitions
- the present invention relates to photostructurable liquid compositions for producing hydrogels based on polyacrylamide.
- Biochips are mostly planar carrier systems made of glass or plastic, the surface of which is equipped with a two-dimensional recognition layer, which comprises biological recognition molecules.
- immobilization layers One problem with the technical implementation of corresponding immobilization layers is first of all the desire for an inexpensive method for applying the layers to the chips or to transducer systems.
- the immobilization systems from liquid precursors are expediently dripped onto a suitable base, dispensed thereon, spun on or printed on.
- To solidify the layers For example, thermal polymerization or crosslinking, drying processes or photochemical polymerization or crosslinking processes are selected.
- Ph. Arquint describes a photocrosslinked hydrogel based on a crosslinked polyacrylamide ("Integrated Blood Gas Sensor for p02, pC02 and pH based on Silicon Technology (dissertation, Ph. Arquint, Uni Neuchatel, Switzerland, 1994).
- Hydrogels play an important role in chemical and / or biochemical analysis and in particular in the implementation of chemo and bio sensors. They serve to create an aqueous environment in a mechanically stable form while at the same time guaranteeing the exchange of materials in a predominantly aqueous environment.
- chemical composition such as network chemistry, mesh size and hydrophilicity, the water content, swelling behavior, mechanical stability, etc. of the hydrogels can be varied over a wide range.
- Hydrogels are particularly attractive in their application in microstructure technology.
- hydrogels in layer thicknesses of a few ⁇ m on transducer structures serve as microchemical reaction spaces in which aqueous chemistry can play out.
- Transducer structures are understood to be electrical, e.g. B. thin-film precious metal electrodes on, for example, a silicon substrate, or optical transducers, such as. B. on glass or plastic surfaces.
- Contact exposure means that the glass mask, the structure of which is to be transferred to the photosensitive layer during the photo process, is placed directly on this layer.
- the photo-crosslinkable layer must therefore be such that the glass mask (glass coated with chrome) can be easily removed again from the exposed layer after the exposure process, without damaging the layer. This is not possible with the system described by Arquint.
- hydrogel precursor Another disadvantage of the system described by Arquint, i.e. The hydrogel precursor can be seen in the fact that there are no reactive linker groups available in the crosslinked layer, with the aid of which chemical or biological recognition molecules are coupled in for analytical applications.
- a hydrogel precursor for the generation of a hydrogel layer by means of photo structuring in contact exposure which also has reactive linker groups, is to be provided.
- the present invention solves this problem by using the basic components of the polyacrylamide hydrogels described by Arquint, such as acrylamide, acrylic or methacrylic-based crosslinking molecules and photoinitiator, by introducing further components which are used to produce a tack-free hydrogel which can be photo-structured in contact exposure - Allow prepress with additional reactive linker groups.
- Arquint such as acrylamide, acrylic or methacrylic-based crosslinking molecules and photoinitiator
- the present invention accordingly relates to a photostructurable liquid composition for producing a hydrogel layer based on polyacrylamide, which is thereby is distinguished by the fact that, in addition to the monomer precursor of the polyacrylamide, the crosslinking agent and the photoinitiator, it comprises at least one film former, at least one comonomer with reactive linker groups and at least one plasticizer.
- a water-swellable hydrogel which contains reactive linker groups for immobilizing chemical or biological recognition molecules for analytical applications and the
- Mass exchange with a predominantly aqueous environment guaranteed.
- the film former is preferably a water-soluble polymer and is selected from the group consisting of polyvinylpyrrolidone, polyacrylamide and / or polyhydroxyethyl methacrylate.
- the comonomer with reactive linker groups is preferably selected from the group consisting of maleic anhydride and / or glycidyl (meth) acrylate. These structures are particularly useful for linking or coupling to functions of chemical and / or biological molecules.
- the composition according to the invention preferably has a plasticizer which is selected from di- and / or triethylene glycol.
- a plasticizer which is selected from di- and / or triethylene glycol.
- composition is preferably in a polar, with Water-miscible solvent.
- Dimethylformamide is particularly preferred.
- the viscosity of the system can be adjusted by varying the solvent and / or the proportion of solvent.
- hydrogel precursor composition As an example illustrating the invention, the following hydrogel precursor composition can be mentioned:
- the solution can be spun onto a substrate, for example a silicon wafer, using a conventional paint spinner.
- Conventional additives can be used to improve the adhesion, or the wafer can be pretreated (see Arquint, op. Cit.).
- the spin-coated layer is then dried by a prebake step and exposed by directly placing the mask on in the conventional contact exposure process.
- the development of non-networked areas as well as the extraction of networked structures, i.e. auxiliary components, uncrosslinked monomers and soluble photoinitiator products can be removed, for example, with water or with water-containing solvents.
- the composition for producing a hydrogel layer has a miscibility of the components used in a widely variable mixing ratio, good adjustability of the viscosity, good spinability and good film formation.
- a tack-free film surface is created.
- the film layer has a photo initiation sufficient transparency for light.
- the crosslinking density and the swellability in water can be set by the proportion of the crosslinking agent and by the proportion of the film former used.
- the auxiliary components such as film formers and plasticizers can be easily washed out.
- the adhesion to the substrate surface can be achieved using conventional adhesion promoter systems, e.g. B. on a silane basis.
