Patent number: 8389959Abstract: The present invention has an object to provide a method for efficiently detecting an image with a smaller number of pixels. The invention relates to fluorescence analysis which uses a substrate having a plurality of regions for being capable of immobilizing biologically-related molecules in positions of lattice points of a lattice structure, and which causes the fluorescence from a certain lattice point to be wavelength-dispersed in a direction other than the direction toward the adjacent closest lattice point. According to an embodiment, for example, the number of pixels of a two-dimensional sensor required for fluorescence analysis of the regions with the biologically-related molecules immobilized can be set to several hundred times to fifty times smaller than that in the conventional case without degrading the measurement accuracy. This can achieve the improvement of throughput, reduction in price, and/or improvement of the operability of an analyzing device.Type: GrantFiled: November 30, 2009Date of Patent: March 5, 2013Assignee: Hitachi High-Technologies Corp.Inventors: Satoshi Takahashi, Tsuyoshi Sonehara, Tomoyuki Sakai, Takanobu Haga, Hirokazu Kato, Nobutaka Kumazaki, Takuya Matsui

Patent number: 8362449Abstract: An object of the present invention relates to observation of single molecule fluorescence while temperature of a sample solution is controlled by a temperature controller and intrinsic fluorescence of the temperature controller is avoided, in a total internal reflection microscope. The present invention relates to provision of an opening at areas of the temperature controller through which incident light and reflected light pass, and configuration adopting a material with intrinsic fluorescence lower than that of the other parts, in a total internal reflection microscope including a prism and the temperature controller. The present invention enables intrinsic fluorescence of the temperature controller to be suppressed, which allows highly sensitive fluorescence observation while controlling sample solution temperature with high precision. For instance, this in turn allows the throughput of single molecule DNA sequencing using a total internal reflection microscope to be improved.Type: GrantFiled: November 30, 2009Date of Patent: January 29, 2013Assignee: Hitachi High-Technologies CorporationInventors: Takuya Matsui, Satoshi Takahashi, Takanobu Haga

Patent number: 8294122Abstract: The present invention aims at reducing background noise derived from a substance that is present in the vicinity of a target substance such as a DNA and protein and attached to the surface of a substrate without an effect on a fluorescent dye labeling the target substance. The substrate that has a probe and is capable of interacting with the target substance is irradiated with noise removing light such that an evanescent field is generated on the surface of the substrate. A target substance and a foreign particle, which are non-specifically stuck to the surface of the substrate, are decomposed by the evanescent field generated by the irradiation with the noise removing light. The evanescent field present near the surface of the substrate has almost no effect on the probe.Type: GrantFiled: March 9, 2009Date of Patent: October 23, 2012Assignee: Hitachi High-Technologies CorporationInventors: Takayuki Obara, Satoshi Takahashi, Akira Maekawa, Takuya Matsui, Nobutaka Kumazaki
