Embodiment Construction

[0204] The best mode for carrying out the invention will now be described with reference to the accompanying drawings. It should be noted that the present invention is not limited to this mode, but can be modified to adopt another mode as long as the mode does not deviate from the subject matter of the present invention.

[0205] FIG. 1 shows a sensor chip and its manufacturing method according to one mode of the present invention. FIG. 1( a ) is a plan view showing a state in which electrodes 2 (detection portions) are formed on a substrate plate 1 . In this example, the electrode 2 is formed with two electrodes and corresponds to the working electrode and the counter electrode, respectively. FIG. 1( b ) is a side view showing a state in which electrodes 2 are formed on a substrate plate 1 . In this example, the electrodes 2 are formed of carbon ink, and are formed by screen printing on the substrate plate 1 made of PET. It should be noted that broken lines in Fig. 1(a) in...

Abstract

A sensor chip is provided. The sensor chip is provided with the board, the cover layer, the spacer layer sandwiched between the board and the cover layer, the hollow reacting part between the board and the cover layer, and a detecting means in the hollow reacting part. The board and the cover layer are made of the same material and have the same thickness. The material and the shape of the spacer layer are symmetric to a flat plane which is parallel to the board at equal distances from the board and the cover layer. The sensor chip does not warp due to changes of temperature and humidity in the environment. A method for manufacturing such sensor chip is also provided.

Description

technical field [0001] The present invention relates to a sensor chip, and more particularly, to a biosensor chip to easily perform quantitative inspection and detection of chemical materials contained in a sample. Furthermore, the invention relates to a method of manufacturing such a sensor chip. In addition, the present invention relates to a sensor chip, especially a biosensor chip, which is produced by the production method of the present invention. Background technique [0002] A biosensor chip is a sensor chip that introduces a tracer sample into the reaction part of the chip, causes the tracer sample to produce a biochemical reaction, such as an enzyme reaction or an antigen-antibody reaction, and outputs it as the result of the biochemical reaction. result information. This biosensor chip employs the excellent molecular recognition function possessed by living organisms, and is attracting attention as a chip capable of quickly and easily measuring trace chemical ma...
