TL;DR: In this article, the luminescence properties of 41 different Eu(III) and Tb(III), chelates that were synthesized with the purpose of developing new markers for chemical and biochemical applications were measured in aqueous solution and their suitability for labels in time resolved immunoassays were evaluated.

TL;DR: In this article, the synthesis and luminescence properties of 20 different chelates composed of 2,2′:6′,2″-terpyridine as the energy absorbing and donating group, EuIIIand TbIII as the emitting ions, methylenenitrilo(acetic acids) as the stabel chelate-forming moieties, and isothiocyanato or (4,6-dichloro-1,3,5-triazin-2-yl)amino groups as the activated moieties for

TL;DR: The spectral and functional properties of the lanthanide-embedded polystyrene nanoparticles developed here suggest that the technology is applicable for high-sensitivity multicolor assays.

TL;DR: The reactivities of the activated luminescent chelates in the labeling of antibodies as well as the effects of both the coupling ratio and the linkage group to the luminescence quantum yield of the antibody-bound chelate were studied in aqueous buffer solution.

TL;DR: A novel, intrinsically fluorescent nonadentate europium chelate with two chromophores and hydrophilic alpha-galactose side groups is synthesized, which facilitates short turnaround times and simple instrumentation due to the absence of all signal development steps, at the same time retaining an excellent immunoassay performance.
