Abstract: According to one embodiment, a chemical sensor including a nucleic acid probe for capturing a target substance, a sensor element that has a surface on which the nucleic acid probe is immobilized, and a liquid film that covers the sensor element is provided.

Abstract: A deodorant carrying urethane foam contains a chemically-reactive deodorant distributed uniformly therein wherein weight loss of said deodorant is not more than 15% when kept at atmospheric pressure and 150.degree. C. for 1 hr. The process of preparing the above-mentioned deodorant carrying urethane foam comprises adding a chemically-reactive deodorant to a urethane foam composition with mixing to permit said deodorant to be uniformly distributed therein, and then causing the resultant mixture to react and produce a foam.

Abstract: A deodorizing urethane foam comprising a urethane foam substrate and a deodorizing component. The deodorizing component is composed of (A) a Diels-Alder reaction-type addition reaction product between an alpha,beta-unsaturated dicarboxylic anhydride and an olefin or a derivative of the reaction product and optionally (B) a copper compound. This urethane foam is produced by foaming a mixture of materials for the urethane foam substrate and the Diels-Alder reaction-type addition reaction product between an alpha,beta-unsaturated dicarboxylic anhydride and an olefin or its derivative of the reaction product and optionally the copper compound.

Abstract: A deodorant composition comprising (A) an acidic phosphoric acid compound and (B) a copper compound and as desired, (C) a reducing agent, and a deodorant composite material comprising a substrate and the deodorant composition included therein.

Abstract: A deodorant composition comprising (A) a compound having an acid anhydride group in a molecule and (B) a copper compound, said deodorant composition being useful as a deodorant composite material comprising a substrate (such as a paper, a fabric, a foamed sheet, a pulp, fibers or an inorganic substance) and the deodorant composition included therein, a deodorant resin composition composed of a thermoplastic resin and the deodorant composition, or a shaped article produced by processing the deodorant resin composition.

Abstract: A composition comprising a copper compound, and blended with it, an oxocarboxylic acid compound. The composition has excellent deodorizing, fungicidal and moldproof properties.

Abstract: A deodorant composition comprising (A) an acidic phosphoric acid compound and (B) a copper compound and as desired, (C) a reducing agent, and a deodorant composite material comprising a substrate and the deodorant composition included therein.

Abstract: A hydraulic cement composition comprising hydraulic cement and a copolymer of 60 to 85 mol % of an alpha,beta-unsaturated dicarboxylic acid and 40 to 15 mol % of an olefin or a water-soluble salt thereof, said copolymer having a number average molecular weight of 300 to 10,000 and containing not more than 10% by weight of a high-molecular-weight polymer having a molecular weight of at least 20,000.

Abstract: A composition comprising a copper compound, and blended with it, (A) an L-ascorbic acid compound and/or an erythorbic acid compound and (B) a hydroxycarboxylic acid compound. The composition has excellent deodorizing, fungicidal and moldproof properties.
