  • Publication number: 20090159849
    Abstract: To provide a fluorescent having low toxicity and high quantum yield, and a method for producing the same. The fluorescent is a compound comprising each one of I, III and VI group elements having a chalcopyrite structure, has a particle diameter of 0.5 to 20.0 nm and a quantum yield of at least 3% but not more than 30% at room temperature. The fluorescent is produced by: mixing a first solution (solution A), which is prepared by dissolving and mixing copper (I) salt and indium (III) salt in a solution added with a complexing agent coordinating copper (I) and indium (III), with a second solution (solution C) in which a sulfur compound is dissolved; ripening the mixed solution for a predetermined amount of time as a pretreatment; heat-treating the ripened solution under predetermined heat conditions; mixing the ripened solution with the second solution (solution C); and heating thus obtained mixed solution under predetermined synthesis conditions.

  • Publication number: 20060211135
    Abstract: A method for simply and efficiently separating substances by utilizing a specific flow behavior in a non-turbulent flow, i.e. a laminar flow, in a micro-channel is disclosed. A mixed solution containing at least two kinds of solute molecules which are different from each other in molecular weight and/or molecular sharp, or at least two kinds of solutions containing their respective solute molecules are flowed into a micro-channel to form a non-turbulent flow. A physical action is given to each molecule by changing the state of flow, thereby causing different behaviors among the different solute molecules. By utilizing this behavior difference, molecules of a specific kind are gathered in a specific region in the channel for separation.

  • Publication number: 20060062701
    Abstract: The present invention relates to a method of manufacturing a micro reactor device that includes a tubular reactor (1) as a flow path, for allowing reaction species to react in the reactor (1). The micro reactor device is manufactured by forming a particle layer (2) on an inner wall of the reactor (1). The particle layer (2) can be formed by causing a dispersion liquid of particles to flow through the reactor (1) and drying. In this way, it is possible to provide a method of manufacturing a micro reactor device having an inner wall modified so that the reaction species can react more efficiently, and to provide the micro reactor device.

  • Publication number: 20050255472
    Abstract: A novel method for analyzing a specimen molecule with high accuracy through a simple operation by forming a laminar flow of a specimen molecule containing solution and a complex forming molecule containing solution in a microchannel and measuring the variation of the degree of diffusion of complexes each composed of a specimen molecule and a complex forming molecule in the laminar flow. The complex forming molecule is fluorescent, and the variation of the degree of diffusion of the formed complexes is measured from the distribution of intensity of fluorescence. The degree of diffusion of the formed complexes can be quantitatively determined by comparing it with a calibration curve preliminarily defined.

  • Patent number: 6963815
    Abstract: A test support program to effectively and reliably check performance of functions which operate with other unspecified servers. A pair of a request message and a response message is stored as a message log. When a processing function based on a program under development being checked outputs a test request message, a computer selects a message log appropriate to the test request message as a template message under preset selection rules. The computer creates a test response message by editing the response message of the selected template message under preset editing rules. Then the computer sends the created test response message as a response to the test request message.
