BACKGROUND Despite their ease of use, lateral flow immunoassays (LFIAs) often suffer from poor quantitative discrimination and low analytical sensitivity. We explored the use of a novel class of europium chelate-loaded silica nanoparticles as labels to overcome these limitations. METHODS Antibodies were covalently conjugated onto europium chelate-loaded silica nanoparticles with dextran as a ...

Ratiometric methods of analysis have been developed for the selective determination of lactate or citrate in microlitre samples of human serum, urine or prostate fluids following comparison of anion binding affinities for a family of nine luminescent europium(III) complexes.

Image and spectral intensity from bicarbonate-selective europium(III) probes localised in the mitochondria of cells is modulated reversibly by variation of external pCO(2), and is suppressed by addition of the carbonic anhydrase inhibitor, acetazolomide.

A high quantum yield and an enhanced photostability was found for a europium(III) tetrakis(2-thenoyltrifluoroacetonate) complex after dissolving the complex in a weakly-coordinating imidazolium ionic liquid.

An europium-chelating [2Fe-2S] cluster was used to assemble an optical molecular chemosensor highly selective for phosphate-containing anions. Phosphate, pyrophosphate, AMP, ADP, ATP, DNA and RNA were well distinguished by UV/V is absorption or fluorescence studies.

The mechanism of quenching of the excited state of terbium and europium complexes by electron-rich reductants occurs by formation of an exciplex involving the triplet excited state of the sensitising chromophore.

Caesium europium polyphosphate, CsEu(PO(3))(4), was synthesized by a high-temperature solution reaction. Its structure is charaterized by a three-dimensional framework made up of double PO(4) spiral chains and EuO(8) and CsO(11) polyhedra.

In this study, hybrid magnetofluorescent structures composed of organic moiety of poly(TMSMA-r-PEGMA) for biomolecules-resistant surfaces and methyl methacrylate for conjugation of europium complex inorganic moiety of magnetic nanoparticles are reported. Lanthanide complex of europium ion with 4,4,4-Trifluoro-1-(2-naphthyl)-1,3-butanedione (NTA) and trioctylphosphine oxide (TOPO)[Eu(NTA)3(TOPO)...
