    摘要: An object of the present invention is to provide a metal particle with which a highly-sensitive testing method can be conducted, and a testing method using such metal particle. The present invention provides a metal particle, which is produced by coating a metal particle labeled with a molecule binding to an analyte with a mixture of two or more types of water-soluble polymer having a mercapto group, a dithiol group or a sulfide group and differing in molecular weight.

    摘要: The present invention provides both crosslinked polymer compositions capable of forming hydrogels upon exposure to an aqueous environment and thiosulfonate hydrogel-forming components. The thiosulfonate hydrogel-forming components of the invention are preferably multi-arm thiosulfonate polymer derivatives that form a crosslinked polymer composition when exposed to a base without requiring the presence of a second cross-linking reagent, redox catalyst, or radiation. Methods for forming hydrogel compositions, as well as methods for using the hydrogels, are also provided.

    摘要: The perfluoroalkylthio-substituted half esters and amides of succinic acid having the formula ##STR1## wherein R.sub.f is a perfluoroalkyl, R.sup.1 alkylene optionally interrupted with oxygen, sulfur or nitrogen atom, X is oxygen or NH, y is zero or 1, Q is a polyether or polyester diradical moiety having a molecular weight of 300 to 5000 or a polysiloxane having 5 to 80 repeating units and A is hydrogen, hydroxyl, amino, alkoxy of 1 to 21 carbons, phenoxy, alkylphenoxy of 7 to 20 carbons, dialkylamino where each alkyl has 1 to 18 carbons or the group ##STR2## said compounds being prepared by first reacting maleic anhydride with a polyether, polyester, diamine or a polysiloxane derivative of an alcohol or a primary amine and then reacting the product with a perfluoroalkyl alkylene thiol. The novel compounds are useful as surfactants with specific applications as wetting agents in coatings, waxes, emulsions, paints and resins.
