摘要:
The present invention relates to a deuteron generating target having a construction for generating deuteron efficiently, and a deuteron generating target apparatus including the same. The deuteron generating target is constructed by providing an upper film mainly composed of a deuterated organic compound onto a base film mainly composed of a halogen-containing organic compound.

A method and apparatus for measuring enzyme activity by supplying a substrate solution and an enzyme solution into a reaction vessel combined with a total reflection absorption prism is disclosed. A measurement solution (40) in which the enzyme solution and the substrate solution are combined together is kept at a constant temperature within the reaction vessel (26) by a temperature control unit (23), and is stirred by a stirrer (21). Infrared light (36) emitted from an infrared light source (3) is made incident on the interface between a total reflection absorption prism (28) disposed in contact with the measurement solution (40) and the measurement solution (40) from the side of the total reflection absorption prism (28) and is totally reflected by the interface. The spectrum of transmitted infrared light (37) thus totally reflected and emitted is detected by an infrared light detector (5). According to thus detected spectrum, a change in the infrared absorption spectrum or absorbance is determined, whereby the enzyme reaction in the measurement solution (40) is measured.
摘要:
This invention provides rotaxane type dyes. Specifically, the rotaxane type dye according to the invention has a rotaxane structure which binds dye molecules to both of the termini of a chain group penetrating a cyclodextrin ring, which possesses excellent water-solubility, and which is capable of having a plurality of different dyes.
