Calibration beads containing luminescent lanthanide ion complexes.
The reliability of lanthanide luminescence measurements, by both flow cytometry and digital microscopy, would be enhanced by the availability of narrowband emitting, UV excited lanthanide calibration beads. 0.5-, 3-, and 5-microm beads containing a luminescent europium-complex are manufactured. The luminescence distribution of the 5-microm beads is measured with a time-delayed light-scatter-gat...
متن کاملPentanuclear tetra-decker luminescent lanthanide Schiff base complexes.
Luminescent pentanuclear tetra-decker Ln(III) complexes [Eu5L4(OH)2(NO3)4(H2O)2].NO3.3H2O , [Nd5L4(OH)2(NO3)5MeOH].3MeOH.2H2O and [Eu5L4(CF3SO3)4(MeO)2(H2O)4].CF3SO3.H2O are formed from Ln(NO3)3.6H2O (Ln = Eu (1), Nd (2)) and Eu(CF3SO3)3, respectively (H2L = N,N'-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine).
متن کاملThermal development of latent fingermarks on porous surfaces--further observations and refinements.
In a further study of the thermal development of fingermarks on paper and similar surfaces, it is demonstrated that direct contact heating of the substrate using coated or ceramic surfaces at temperatures in excess of 230°C produces results superior to those obtained using hot air. Fingermarks can also be developed in this way on other cellulose-based substrates such as wood and cotton fabric, ...
متن کاملThe detection of latent fingermarks on porous surfaces using amino acid sensitive reagents: a review.
The introduction of ninhydrin treatment as a chemical technique for the visualisation of latent fingermarks on porous surfaces revolutionised approaches to forensic fingermark examination. Since then, a range of amino acid sensitive reagents has been developed and such compounds are in widespread use by law enforcement agencies worldwide. This paper reviews the development and use of these reag...
متن کاملControlled assembly of luminescent racks based on heteroleptic dinuclear lanthanide complexes.
Luminescent lanthanide racks are formed in solution through supramolecular assembly of lanthanide ions with a rigid bis-didentate sensitiser ligand and octadentate aminopolycarboxylate ligands.
