- each suspension A detection substance arrangement device for controlling to place the parallel line-like narrow not in contact with each other on placed on the stage film.
- Line contact includes “line intersection”.
- a “pipe” is a pipe-like member through which liquid can pass or be retained, and may be both removable and non-removable from the body.
- Line is usually a straight line, but may be a curved line.
- Detection substance refers to a substance to be detected in order to determine the unknown structure of the target substance or to perform various other analyzes or analyzes of the target substance, such as DNA, RNA, and oligonucleotide. Genetic materials, biological macromolecules such as proteins and sugars, or microorganisms such as bacteria and viruses or biological tissues such as cells.
- one or a plurality of pipes one or a plurality of reservoirs each containing a suspension containing various kinds of substances for detection and communicating with the pipes, and the pipe or the reservoir.
- a printing press having discharge means for discharging the suspension by adjusting the pressure in the section, a regenerating section for cleaning or replacing the pipeline storage section, and a film on which printing is performed by the printing press.
- a stage to be mounted a moving unit that allows the pipeline to move relatively to the reproducing unit and the stage, and a control unit that controls the moving unit and the discharging unit.
- the control unit repeats the discharge and the movement of the suspension containing the detection substance with respect to the pipeline, and the washing or replacement of the pipeline and the storage unit to thereby repeat the suspension.
- the liquid was placed on the stage Control so that they are arranged in narrow parallel lines that do not touch each other on the film. This is a detection substance arrangement device.
- a third aspect of the present invention provides a liquid holding end such as one or more grooved needles, cylinders, pens, and line-shaped imprinted portions, a regeneration unit that cleans or replaces the liquid holding end, and various types of detection.
- a container having a plurality of liquid storage portions in which the respective liquid suspensions containing the liquid substances are stored and into which the liquid holding ends can be inserted; and a film on which the liquid holding ends are applied, written or stamped.
- the control unit repeats holding, moving, and washing or replacing the suspension containing the detection substance with respect to the liquid holding end, so that the respective suspensions are placed on the stage. Narrow widths that do not touch each other on the loaded film.
- the “holding end” refers to a member, such as a pen tip, capable of holding a liquid and outputting by leakage or oozing of the liquid.
- a storage portion that can communicate with the liquid holding end and can supply the suspension may be provided. In this case, the regenerating section is cleaned or replaced with the liquid holding end and the storage section.
- the regenerating unit may be configured such that the pipe, the liquid holding end, or the pipe and the storage unit cannot be attached to or detached from the main body. Is a cleaning tank into which these conduits or liquid holding ends can be inserted and in which a cleaning liquid is stored, and the conduits, the liquid holding ends, or the conduits and the reservoir are detachable from these main bodies. If it is provided in the, it is a detachable part to which these are removed and a new pipeline, liquid holding end or pipeline and storage part are mounted.

- Step S2 to Step S5 is performed on the suspension of the substance for detection in (12) of the second step.
- the second position is a position displaced from the first position so as to have an interval that avoids contact with the already arranged line 31. In this example, it is a position displaced in the lateral direction by a distance of 1/8 of the interval 46.
- 96 kinds of detection substances are applied to the film 22. Can be arranged in parallel lines.
- step S6 the detection substance is immobilized on the film 22 by reacting, binding or attaching the detection substance and the fixing substance in the placed suspension. Dry the suspension.
- step S7 the immobilized film 22 is wound and bound around the above-mentioned winding core 24 by using the winding device 23, and the whole is formed into a columnar shape.
- step S8 the wound and bound film 22 is thinly cut in a direction perpendicular to its axial direction to produce a large number of detection substance supports.
- steps S1 to S6 correspond to an arrangement process
- Step S7 is an integration step
- step S8 corresponds to a cutting step.
- a pretreatment step may be provided before step S1 to coat the film 22 with latex, foamed resin, fine beads, or the like, or to process grooves or the like.
- Step S1 is not necessary when the film 22 itself is a material having a property of fixing a substance for detection or is processed in such a manner.
- the post-processing of the film 22 on which the substance for detection is arranged A process may be added.
- an adhesive, an ultraviolet curable resin, or the like may be applied using the roller device 42 in order to bind the film 22 when wound up.
- step S8 can be performed between step S6 and step S7 before winding by using the cutting and winding device 110.
- cutting may be performed simultaneously with step S7.
- each of the above components, each film, or each device can be used in any combination while appropriately deforming.
- the substance for detection is arranged mainly in the form of a film using a dispenser
- the detection substance support is a disk, but may be a square.
- the detection substance is an oligonucleotide
- the present invention is not limited to this case, and other genetic substances, proteins, immune systems, biopolymers such as sugars, and the like, It may be a living tissue.
