Definitions
- the invention relates to a method for the production of synthesis or analysis series, in which the smallest variable volumes of different starting materials are combined to form a large number of different accumulation products and, if appropriate, examined with regard to certain physical and / or chemical properties, and to an apparatus for carrying out the method.
- photometers are used for quantitative and qualitative analysis.
- Samples of biological origin for example blood
- a Reagent or several reagents mixed which react with the component to be detected in the sample. This reaction causes a specific change in the optical properties of the mixed product, which is detected with the photometer and recorded quantitatively.
- the invention is therefore based on the object of specifying a method with which a multiplicity of precisely metered substance accumulations from two or more starting materials in different compositions and / or concentrations can be provided and, if appropriate, investigated in a very short time and with little outlay on equipment.
- the object in a method for the production of synthesis and analysis series according to the
- the preamble of claim 1 is solved in such a way that the accumulation products according to the inkjet printer principle are formed in a program-controlled manner at predetermined positions on an essentially planar substrate by the finest droplets or jets of the liquid, which can function as an exchangeable printhead and move linearly back and forth Material discharge head stored starting materials are applied to the surface of the substrate according to a specific computer program with regard to their respective dosage and positioning, and the accumulation products are subsequently analyzed in an analysis by a sensor connected to a linearly movable measuring head at the programmed positions, the substrate line by line a direction perpendicular to the linear movement of the material dispensing head or the measuring head is moved.
- the basic idea of the invention lies in the use of an inkjet printer connected to a computer for producing a large number of synthetic products or mixtures of substances or reaction products which differ in their material and quantitative composition for a subsequent investigation with regard to certain properties or effects, the presence of active substances, etc .. That is, the known active principles of an inkjet printer trained for color printing are used, which in the program-controlled spraying of different substances and quantities of substance onto a base by controlled opening and closing of the respective nozzles of the material dispensing head connected to storage containers or electrostatic or magnetic deflection of the unwanted material beams exist to synthesize products or accumulation products for a subsequent analysis on a surface to produce formed substrate.
- the material dispensing head can be made in one piece with several storage containers for different, separately controlled Nozzle channels can be formed, or a plurality of material dispensing heads, each with a storage container, can be provided in a depot, in which case the corresponding material dispensing head is activated in accordance with the material to be dispensed.
- the material discharge head and the measuring head are arranged separately from each other. However, it is also conceivable to train both as one unit. ⁇ ⁇
- the invention is used in the production of extensive synthesis series and analysis series, for example ELISA test with microtiter plates, in the creation of tests with combinatorial libraries or DNA chips, in cell differentiation, in the execution of tests in the field of dry chemistry and in vitro diagnostics or used in the photometric analysis of reaction kinetics.
- both the individual material components and the substrate have a specific, coordinated surface tension in order to prevent the substances or the substance mixture from running on the substrate.
- the substrate consists of a flexible material, such as paper or plastic film, or of a rigid base, for example made of glass, plastic or the like.
- the substrate has a large number in a suitable manner, for example, lithographically produced depressions in the starting materials for the produced synthesis product or - that are then injected under investigation analysis product from the various reservoirs of the material dispensing head.
- the accumulation products are generated in a protective gas atmosphere, in a vacuum or under a certain temperature and / or pressure regime.
- the starting materials can also be heated themselves, if necessary, to bring them into a flowable state which can be easily discharged from the storage containers (material chambers) of the material dispensing head.
- the substrate is prepared with certain substances in order to trigger an optical reaction for the analysis, for example.
- a serum sample is to be examined for the presence of certain components, such as albumin, cholesterol, glucose and others.
- certain components such as albumin, cholesterol, glucose and others.
- the albumin present in a serum with bromocresol green should be detected.
- the material chambers assigned to the print head acting as the material output head of a color jet printer ⁇ from each of which separate nozzle channels lead to the material output head, with the serum and with different reagents which, when mixed with the serum, are capable of mixing a specific enzyme into a certain color reaction with the serum to prove the serum, filled.
- the material delivery head which can be moved back and forth on a rail, is connected to a computer. His movements too predetermined
- the substrate used here is a transparent plastic film that, like in a printing process with an inkjet printer, is moved perpendicular to the direction of movement of the material dispensing head after a line on the substrate has been filled with the mixtures of sample and reagents.
- the individual mixtures on the substrate which are now illuminated by a light source, are run over by the measuring head under program control, whereby a attached to this sensor Measures the color and intensity of the light emanating from the illuminated mixture.
- the measurement results are forwarded to the computer and analyzed by it.
- the application of the mixtures and their scanning of the sensor is carried out while measuring the air pressure, the air humidity and temperature, or under ⁇ ⁇ predefined external conditions, so that the examination is also reproducible. It is also conceivable that with the sequential supply of several samples to the sample chamber and with the use of intermediate washing processes, different serum samples are applied to the substrate film.
- the method according to the invention is used to produce synthetic products from different amino acids.
- a quartz plate with a large number of depressions formed by lithographic etching is used as the substrate.
- the individual wells are controlled one after the other by the material dispensing head with its material chambers receiving the various starting substances, in order to use them in accordance with the ink jet printing process in the specified sequence and dosage
