Singlet-Triplet Excitations and High-Field Magnetization in CuTe2O5

By measuring the THz electron spin resonance (ESR) transmission spectra and high-field magnetization on the spin-gapped system CuTe2O5, we identified the singlet-triplet excitations in the dimerized non-magnetic ground state. The determined spin-gap value ...

Binding of Biotin to Streptavidin: A combined fluorescence correlation spectroscopy and time-resolved fluorescence study

Mostafa Shalaby

The Biotin-Streptavidin complex is a widely studied system in biology and biophysics, because of its extremely strong non-covalent binding affinity. The latter is often exploited to link molecules to substrates or to one another. However, the details of th ...

Excitation and Reemission of Molecules near Realistic Plasmonic Nanostructures

Olivier Martin, Andreas Kern

The enhancement of excitation and reemission of molecules in dose proximity to plasmonic nanostuctures is studied with special focus on the comparison between idealized and realistically shaped nonostructures. Numerical experiments show that for certain ap ...

N-Aryl Chromophore Ligands for Bright Europium Luminescence

Rosario Scopelliti, Jean-Claude Bünzli, Svetlana Eliseeva

Sterically hindered N-aryl-benzimidazole pyridine-2-carboxylic acids (aryl = phenyl, 4-biphenyl, 2-naphthyl) readily form homoleptic, neutral, nine-coordinate europium complexes which display efficient sensitized luminescence in solid state and in dichloro ...

Triplet imaging of oxygen consumption during the contraction of a single smooth muscle cell (A7r5)

Dimitri Nestor Alice Van De Ville, Theo Lasser, Kai Johnsson, Marcel Leutenegger, Boris Hinz, Iwan Märki, Thiemo Spielmann, Aurélie Formey de Saint Louvent

The measurement of tissue and cell oxygenation is important for understanding cell metabolism. We have addressed this problem with a novel optical technique, called triplet imaging, that exploits oxygen-induced triplet lifetime changes and is compatible wi ...
