A two-probe tandem DNA hybridization assay including capture DNA(1), probe DNA(2), and target DNA(3) was prepared. The long-lived luminescent europium complex doped nanoparticles (NPs) were used as the biomarker. The complex included in the particle was Eu(TTA)(3)(5-NH(2)-phen)-IgG (ETN-IgG), the europium

A polymerizable ligand, 5-acrylamido-1,10-phenanthroline (L), was synthesized. Its Eu(III) complex with 2-thenoyltrifluoroacetone (HTTA) was prepared and characterized by elemental analysis, IR, MS, and (1)H NMR spectra. The photophysical properties of the complex were studied in detail by using UV, luminescence
