    摘要: In the conventional nucleic acid analysis devices and nucleic acid analyzers, there was no technique available for sequencing a single nucleic acid molecule easily and highly efficiently. The present invention enabled a highly efficient single molecule immobilization of nucleic acid with good reproductivity in a short time at a low price by providing small metallic bonding pads at predetermined positions on a support substrate, firmly fixing a hydrophobic linker on the bonding pads, and bonding on to the linker bulky microparticles onto which a single molecule of a nucleic acid sample fragment is immobilized. According to the present invention, in the nucleic acid analysis device which uses a nucleic acid analyzer, the nucleotide read length can be extended and many types of nucleic acid molecule to be analyzed can be analyzed at one time.

    摘要: An object of the present invention is to regularly align microparticles, on each of which a nucleic acid synthetase or a DNA probe capable of capturing a nucleic acid sample fragment is immobilized, on a support so as to improve throughput of nucleic acid analysis. The present invention relates to a method comprising immobilizing a nucleic acid synthetase, a DNA probe, or the like in advance to a microparticle, forming a pattern of metal pads each having a diameter smaller than the microparticle diameter with gold or the like on a support, and allowing a microparticle to be bound to the pads via a chemical bond. In addition, when the surfaces of microparticles are electrically charged, a pattern of metal pads each having a diameter equivalent to or larger than the microparticle diameter is formed with gold or the like on a support and a microparticle is allowed to be bound to the pads via a chemical bond. According to the present invention, many types of nucleic acid fragment samples can be regularly aligned at a high density and immobilized on a support. This allows high throughput analysis of nucleic acid samples. For example, if microparticles are immobilized at 1-micron pitches, a high density of 106 nucleic acid fragments/emm2 can be readily achieved.
