Abstract: The storage case has a structure in which a sample storage case (S) contained in a storage case is cooled and held at a low temperature by a Stirling refrigerator. A detection element is disposed in a room-temperature area of the storage case. The chemical or physical property of the detection element varies when a contaminant adheres to the detection element. Entrance of a contaminant into the storage case can be checked by contactlessly checking the detection element from the outside of the storage case. The storage case includes a server for receiving the result of the check from the detection device, storing the result, and setting up connection via a communication line to at least two out of a terminal operable by the forwarder, a terminal operable by the carrier, and a terminal operable by the recipient to transmit the result to the two.

Abstract: Biomolecular and other interactions are analyzed with a simpler construction. A biotic sample is fixed to noble metal nanoparticles, and light is irradiated from a light source to the noble metal nanoparticles through an optical fiber. Light obtained after reflection of the irradiated light by the noble metal nanoparticles is introduced to one or more optical detecting units through another optical fiber. The optical detecting unit(s) separately measure the intensity of the input light in a second band including a maximum absorption wavelength, a first band covering a longer wavelength range than the range covered by the second band, and a third band covering a shorter wavelength range than the range covered by the second band.

Abstract: Obtained is a biomolecular interaction analyzer which is capable of simultaneously measuring a large number of many kinds of samples. The biomolecular interaction analyzer is an analyzer for measuring biomolecular interactions, which includes a measurement chip and a color CCD array. The measurement chip includes a plurality of measurement areas in each of which a fine particle sensor coated with a noble metal is formed. In the color CCD array, two-dimensionally arrayed light receiving elements respectively for measuring optical properties of the measurement areas are utilized.

Abstract: In a molecular interaction detector, a noble-metal free-electron thin film is formed on a substrate. Styrene-made nanoparticles are adsorbed onto the thin film surface. Another noble-metal free-electron thin film is formed on upper-half surfaces of the nanoparticles and is modified by an organic linker molecule. The organic linker molecule has a linear or branched chemical structure including a functional group capable of being fixed to the surface of the noble-metal free-electron thin film with a linear chain made of 1 to 5 atoms. A detergent is used in a mobile phase. Deposition of materials having no relation with the measurement onto a sensor can be avoided in the molecular interaction detector.
