    摘要: The invention concerns an ion-selective electrode comprising a polymer membrane, and its manufacturing procedure. Selectivity of the electrode to a given ion has been achieved in that the membrane is of material polymerized from a substance or mixture of substances containing the ion in question and from which after the polymerizing step a quantity of ions of this kind has been removed so that gaps of equivalent size have been produced in the material. An example of said polymerizable substances is a mixture formed by allyloxy-substituted propyleneglycol phosphate and calciumbisdiallyl phosphate, which is used in making a calcium-selective electrode. If in the example mixture calcium is replaced by another ion, an electrode which is sensitive to this particular ion is similarly obtained. It is to advantage in view of the electrode's mechanical properties to make the electrode without internal solution by affixing the polymer membrane directly on the surface of a semiconductor body consisting e.g. of stannic dioxide.

    摘要: A method of conducting assays for analytes, usually from biological samples, utilizing bioaffinity reagents linked to luminescent lanthanide chelates, which are synthesized so that the non-radiative quenching of the ion luminescence through C--H bond vibrational energy manifolds is avoided using a stable chelate where the CH and CH.sub.2 groups in the vicinity of the emittive ion are substituted with CD and CD.sub.2 groups hence producing improved luminescence quantum yield and higher assay sensitivities.
