Time-resolved luminescence microscopy of bimetallic lanthanide helicates in living cells

Jean-Claude Bünzli, Anne-Sophie Chauvin, Caroline Vandevyver, Bo Song

The cellular uptake mechanism and intracellular distribution of emissive lanthanide helicates have been elucidated by time-resolved luminescence microscopy (TRLM). The helicates are non-cytotoxic and taken up by normal (HaCat) and cancer (HeLa, MCF-7) cell ...

Ultrafast Photoinduced Charge Separation in Naphthalene Diimide Based Multichromophoric Systems in Liquid Solutions and in a Lipid Membrane

Natalie Renuka Banerji, Stefan Matile, Eric Vauthey, Alexandre Fürstenberg

The photophysical properties of multichromophoric systems consisting of eight red or blue naphthalene diimides (NDIs) covalently attached to a p-octiphenyl scaffold, as well as a blue bichromophoric system with a biphenyl scaffold, have been investigated i ...

Molecular wiring of LiFePO4 (Olivine)

Michael Graetzel, Ladislav Kavan

The carbon-free LiFePO4 (olivine) was modified by a monolayer coverage with [12-(2,5-di-tert-butyl-4-methoxy-phenoxy)-dodecyl]-phosphonic acid, coded DW. Thin film electrodes were bonded with 5% PVDF and deposited on F-doped SnO2 (FTO) support. The surface ...

Potentiometric platform for the quantification of cellular potassium efflux

Nico de Rooij

Renewed interest in the measurement of cellular K+ effluxes has been prompted by the observation that potassium plays an active and important role in numerous key cellular events, in particular cell necrosis and apoptosis. Although necrosis and apoptosis f ...

Laboratory and ALT-Evaluation of high stiffness underlayers with high percentage of re-use as developed in the NR2C- project

André-Gilles Dumont, Nicolas Bueche

New Road Construction Concepts (NR2C) is a project of FEHRL supported by the European Commission under the Sixth Framework Programme. This project aims at developing perspectives and specific innovations in different transport areas. One of the ideas conce ...

Modelling and microfabrication of a polyimide-based 3D tissue coupled electrodes for electrical stimulation in the chick retina

Philippe Renaud, Sri Harsha Kasi Raj

We present a new flexible microfabricated polyimide-based platinum array of 3D “tissue coupled electrodes” (TCEs) applied for local stimulation of the chick retinal photoreceptor layer and simultaneous patch clamp recording from a single retinal ganglion c ...

Regulation of the V-ATPase along the endocytic pathway occurs through reversible subunit association and membrane localization

Françoise Gisou van der Goot Grunberg, Céline Lafourcade

The lumen of endosomal organelles becomes increasingly acidic when going from the cell surface to lysosomes. Luminal pH thereby regulates important processes such as the release of internalized ligands from their receptor or the activation of lysosomal enz ...

Study of the electrochemical oxidation process of 3,4-(methylenedioxy)phenylmethanol in non-aqueous solvents

Fernando Cortes Salazar

The electrochemical oxidation of 3,4-(methylenedioxy)phenylmethanol (piperonyl alcohol) was characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Two electrochemical oxidation signals were found for piperonyl alcohol. T ...

Microfabricated Structures Powered by Flagellated Bacteria

Mahmut Selman Sakar

We have studied self-coordinated transportation systems using SU-8 microstructures in open microchannels and here present a stochastic model for the bacteria-driven microbarge that is designed to mimic the motion of this system with and without chemical gr ...
