Definitions
- the present invention relates to a microchip having a flow path and a method for manufacturing the microchip.
- a microchip that performs chemical reaction, separation, and analysis of a liquid sample such as nucleic acid, protein, and blood in a minute space, or an apparatus called ⁇ TAS (Micro Total Analysis Systems) has been put into practical use.
- ⁇ TAS Micro Total Analysis Systems
- a method for joining a resin substrate and a resin sealing member As a method for joining a resin substrate and a resin sealing member, a method using an adhesive, a method in which a resin surface is melted with a solvent, a method using ultrasonic fusion, a laser fusion, and the like are used. A method of using, a method of using heat fusion, and the like are known.
- a flat plate-shaped sealing member is joined to form a flow path, it is difficult to generate a uniform flow path if any distortion or warping occurs in the shape of the base material and the sealing member.
- the microchip in which a resin film is bonded to a resin substrate on which fine channel grooves are formed has been studied.
- the microchip is made of resin in which a channel groove is formed on the surface and through holes (reagent introduction / discharge holes, sometimes called wells) provided at the end of the channel groove, etc. It is produced by a substrate and a resin film bonded to the surface of the resin substrate.
- the resin surface is dissolved with a solvent.
- a method using ultrasonic fusion, a method using laser fusion, a method using thermal fusion with a flat plate-shaped or roll-shaped pressure device, and the like Especially, since heat fusion can be implemented at low cost, it is suitable as a joining method on the premise of mass production.
- the resin substrate and the resin film are thermally bonded by a hot press machine, and after bonding, the microchip is observed. Was mixed.
- the factors related to temperature are as follows.
- the heating temperature is different, a temperature gradient is generated in the microchip, heat distortion occurs, and the microchip warps. In this case, in most cases, warping remains even after cooling.
- Even if the heating temperature on both sides is the same, there is a difference in thermal expansion, thermal conductivity, and heat capacity between the resin substrate and the resin film, so the resin substrate and the resin film are evenly distributed. It is difficult to heat and causes warping of the microchip.
- the resin film side may have to be heated and joined, which makes it difficult to suppress warpage.
- the factors related to pressure are as follows. In thermal bonding, a pressure is applied to hold a resin substrate and a resin film and make them adhere and degas, but the pressure distribution in the microchip also causes warping. The most ideal case is when pressure is evenly applied from the resin substrate side and the resin film side. Since the pressure also changes depending on the elastic modulus, bending strength, and surface hardness of the resin substrate and the resin film, the material and dimensions of the resin substrate and resin film can be selected as appropriate, but for analysis using a microchip. Suitable materials, dimensions, and those suitable for joining do not necessarily match, so it is difficult to apply pressure evenly, that is, to suppress warping.
- a method of applying pressure (1) a method of rotating while sandwiching with a roller from both sides of a resin substrate and a resin film, and (2) a roller for holding the resin film side, and holding it on the resin substrate side
- the method include a method of rotating a flat plate while pressing the flat plate with a roller, and (3) a press method in which a resin substrate and a resin film are sandwiched between parallel plates.
- the method of rotating while sandwiched between rollers (1) is a very effective method for joining resin films, but since the resin substrate of the present invention is an injection molded product, it is continuously like a resin film. Therefore, it is difficult to set the resin substrate and the resin film between the two rollers and to join them without shifting the shafts that are the centers of pressure of the two rollers. If the resin substrate and the resin film are displaced, bubbles and bubbles are mixed, and if the center axis of the roller is displaced, pressure is applied non-uniformly, causing the resin substrate to warp.
- the method (2) of rotating while pressing the flat surface with a roller can easily fix the resin substrate on the flat plate, but the contact surface where the roller contacts the resin film is linear.
- the contact surface on which the flat plate contacts the resin substrate is planar, pressure is applied non-uniformly and the resin substrate is warped.
- the press method (3) has the advantage that it is easy to apply pressure uniformly.
- the resin film is squeezed and cannot be bonded while removing bubbles, and the bonding surface of the resin substrate and the bonded surface of the resin film are not bonded. Since it is directly bonded, air bubbles are easily mixed. In addition, considerable pressure is required to remove the bubbles, and it becomes impossible to maintain the shape of the fine channel that has been precisely transferred.
- the flat plate and the resin film are in close contact, or the flat plate and the resin substrate are in close contact, sticking is likely to occur, and the microchip is not sufficiently cooled when the microchip is peeled off from the flat plate. There is also a problem that the microchip is deformed.
- Microchip warpage has the following three problems.
- the first problem is that the appearance quality of the microchip is not good.
- the second problem is that the positioning accuracy when the microchip is set in the analyzer is lowered. A decrease in accuracy results in a decrease in analysis accuracy.
- detection is generally performed in a fine flow path of several tens of microns, positioning when the microchip is set in an analyzer is important.
- the third problem is that the heat conduction varies and the heat conduction decreases. Variations and reductions in heat conduction result in reduced analytical accuracy.
- the entire microchip may be heated and cooled.
- it is desirable that the microchip is in close contact with the heating source and the cooling source.
- it is necessary to cool with a water-cooling jacket or a Peltier element so that the liquid in the fine channel and the analyte do not heat and boil.
- the allowable amount of microchip warpage is as follows.
- the allowable amount of warpage depends on the dimensions of the microchip and the conditions under which the microchip is used, so it cannot be generally stated. However, if the warp angle is within 5 milliradians, the level that can be used by firmly pressing the microchip is 2. If it was within milliradians, it was a level that could be used without pressing the microchip. Of course, it is desirable that there is no warp.
- a jig having a claw portion for fixing the resin substrate is used, and when the resin substrate and the resin film are thermally bonded from a roller, the four corners of the resin substrate are clawed.
- the resin film could not be joined to the peripheral part including the four corners of the resin board pressed by the claw part, or made of resin There is a problem that the strength for joining the films is not sufficient.

Then, the system (2) is adopted in which the stage 40 is rotated while being pressed by a roller. Although the microchip warpage occurs in the method (2), the method (1), the resin substrate 10 and the resin film, which are rotated while being sandwiched by rollers from both sides of the resin substrate 10 and the resin film 20, as described above. Compared with the press method (3) in which the plates 20 are sandwiched between the parallel plates, the resin film 20 is less susceptible to wrinkles, bubbles, and flow path deformation.
