摘要:
A microflow path system has a column layer of at least 0.5 mm in internal diameter. The column layer includes a hybrid-forming section and a fluid-supply promoting section arranged in a region downstream of the hybrid-forming section. The hybrid-forming section is packed with beads to provide a bead bed length of not longer than 4 mm. The fluid-supply promoting section serves to contribute to an increase in a flow rate of a fluid supply.
摘要:
The present disclosure provides a nucleic-acid extraction method for carrying out the following procedures in the same cell, the procedures including: performing an ultrasonic process on a sample containing a nucleic acid; adsorbing substances contained in the sample by making use of an adsorption carrier; and condensing the nucleic acid by damming the nucleic acid moving in an electrophoresis phenomenon. In accordance with the nucleic-acid extraction method, it is possible to carry out an ultrasonic process, an adsorption process and an electrophoresis process in the same cell. Thus, it is possible to eliminate an operation to transfer the sample from one cell to another one for each of the processes.

摘要:
A bead set is composed of plural subsets of beads. The beads in each subset are each provided with a surface permitting immobilization thereon of a substance that takes part in a predetermined corresponding reaction or interaction. The individual beads in the beat set are provided with different physical elements, respectively, such that the individual beads in the bead can be distinguished into the plural subsets through an analysis of captured images of the individual beads in the bead set by a computer.

A method of measuring an enzymatic activity, includes measuring the quantity of a substrate metabolite produced upon metabolism of a substrate by an enzyme, through detecting a radiant wave generated from a multiple photon excitation process of the substrate or the substrate metabolite.
摘要:
A flow path system suitable for use in the detection of hybridization includes a capillary provided at a predetermined location thereof with a reaction section packed with beads. On the beads, a linker having a sequence of bases of the same type is immobilized, and a target nucleic acid complementarily bound to the sequence of the bases of the same type is held.

A projection screen comprises a red-reflecting particle layer, green-reflecting particle layer and blue-reflecting particle layer sequentially stacked on a substrate. In each particle layer particles are accumulated by eleven cycles in a regularly alignment such as close-packed structure. Diameter of red-reflecting particles is approximately 280 nm, diameter of green-reflecting particles is approximately 235 nm, and diameter of blue-reflecting particles is approximately 212 nm. Each particles layer is accumulated by self-organized technique. The substrate used here can absorb light of wavelengths other than those of red, green and blue three primary colors.
摘要:
An optical state modulation method is provided. The method comprises steps of periodically modulating luminance of a visible light in temporal domain so as to generate an optical state variation on a recorded image that is obtained by image-capturing of a displayed image, the visible light being superposed on an original display image to produce the displayed image, the optical state variation being independent of an original display image and generating no hampering effect when the displayed image is directly watched.
