Electrostatic co-assembly of iron oxide nanoparticles and polymers : towards the generation of highly persistent superparamagnetic nanorods

A paradigm proposed recently by Boal et al. (A.K. Boal et al., Nature 404, 746-748, 2000) deals with the possibility to use inorganic nanoparticles as building blocks for the design and fabrication of colloidal and supracolloidal assemblies. It is…

How Gold Particles Suppress Concentration Quenching of Fluorophores Encapsulated in Silica Beads

Increasing the luminescence of silica particles encapsulating fluorescein by increasing fluorescein concentration is a promising strategy which is unfortunately limited by the phenomenon of self-quenching. In this paper, we demonstrate that this…

Développement de guides d'ondes planaires de TiO2 optiquement actifs pour biopuces à ondes évanescentes

Les biopuces sont utilisées en biologie moléculaire et pour le diagnostic. La lecture est généralement réalisée en «end-point» mais le suivi en temps réel donne accès à des données complémentaires. Avec les biopuces à fluorescence, ces expériences…

Epitaxial Growth of Highly Oriented Fibers of Semiconducting Polymers with a Shish-Kebab-Like Superstructure

Highly oriented fibers of regioregular poly(3-alkylthiophene)s (P3ATs) showing a ldquoshish-kebabrdquo morphology are prepared by oriented epitaxial crystallization in a mixture of 1,3,5-trichlorobenzene (TCB) and pyridine. The superstructure of the…

New Hindered BODIPY Derivatives: Solution and Amorphous State Fluorescence Properties

Four new hindered boron-dipyrromethene (BODIPY) dyes have been engineered and synthesized by modification of the pyrrole substituents. The chromophores were designed to shift their absorption and emission wavelengths to the red and to show…

Laser operation in non-doped thin films made of a small-molecule organic red-emitter

Stimulated emission in small-molecule organic films at a high dye concentration is generally hindered by fluorescence quenching, especially in the red region of the spectrum. Here we demonstrate the achievement of high net gains (up to 50 cm-1)…
