Sunshine and a pinch of tropical soils: A natural, low-cost photo-Fenton variation for safer water, assisted by H2O2 or percabonate

César Pulgarin, Michaël Bensimon, Stefanos Giannakis, Thomas Guillaume

Clean water is essential for human survival, but access to safe drinking water remains a challenge in resource -limited regions. Herein, we explored a low-cost but effective solution for water potabilization using natural iron sources from soils along with ...

Classification of Metal-Based Drugs according to Their Mechanisms of Action

Paul Joseph Dyson

Metal-based drugs and imaging agents are extensively used in the clinic for the treatment and diagnosis of cancers and a wide range of other diseases. The current clinical arsenal of compounds operate via a limited number of mechanisms, whereas new putativ ...

Inkjet-Printed Carbon Nanotube Electrodes Modified with Dimer-captosuccinic Acid-Capped Fe3O4 Nanoparticles on Reduced Graphene Oxide Nanosheets for Single-Drop Determination of Trifluoperazine

Hubert Girault, Andreas Stephan Lesch, Milica Jovic

Here we report the design of a disposable single-drop voltammetric sensor for the quantitative determination of antipsy-chotic drug trifluoperazine (TFP). The sensor was build using inkjet-printed carbon nanotube (CNT) electrodes which were modified with d ...

Emergence of Mycobacterium leprae Rifampin Resistance Evaluated by Whole-Genome Sequencing after 48 Years of Irregular Treatment

Stewart Cole, Andrej Benjak, Charlotte Avanzi, Philippe Busso

A case of Mycobacterium leprae rifampin resistance after irregular antile- prosy treatments since 1971 is reported. Whole-genome sequencing from four longi- tudinal samples indicated relapse due to acquired rifampin resistance and not to re- infection with ...

Slowing the Kinetics of Alumina Sol-Gel Chemistry for Controlled Catalyst Overcoating and Improved Catalyst Stability and Selectivity

Jeremy Luterbacher, Florent Emmanuel Héroguel, Yuan-Peng Du

Catalyst overcoating is an emerging approach to engineer surface functionalities on supported metal catalyst and improve catalyst selectivity and durability. Alumina deposition on high surface area material by sol–gel chemistry is traditionally difficult t ...

Chelating agents as coating molecules for iron oxide nanoparticles

Heinrich Hofmann, Josefina Adriana Maria Bastiaansen, Marijana Mionic Ebersold, Débora Bonvin

Due to their high chemical affinity towards metal ions, chelating agents (CAs) have been used for decades for water purification, but also for protection against metal intoxication and in nanomedicine as linking molecules at the surface of nanoparticles. H ...

Bioavailable copper modulates oxidative phosphorylation and growth of tumors

Johan Auwerx, Douglas Hanahan, Carole Poitry-Yamate, Pénélope Andreux, Seiko Ishida

Copper is an essential trace element, the imbalances of which are associated with various pathological conditions, including cancer, albeit via largely undefined molecular and cellular mechanisms. Here we provide evidence that levels of bioavailable copper ...

Dinuclear Gd(III) Polyaminocarboxylates as Building Blocks for MRI Contrast Agents

Bibimaryam Mousavi

Magnetic resonance imaging (MRI) technique is at the forefront of biomedical and clinical imaging. Its superb spatial resolution, noninvasive nature and use of benign radiation outweigh its intrinsic low detection sensitivity. However paramagnetic relaxers ...

Lanthanide Bimetallic Helicates for in Vitro Imaging and Sensing

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

As the need for targeting luminescent biolabels increases, for mapping selected analytes, imaging of cells and organs, and tracking in cellulo processes, lanthanide bimetallic helicates are emerging as versatile bioprobes. The wrapping of three ligand stra ...

Study of peptide on-line complexation with transition-metal ions generated from sacrificial electrodes in thin-chip polymer microsprays

Hubert Girault, Tatiana Rohner

A miniaturized polymer electrospray-type interface is used to study metal-ion chelation with model peptides. Taking advantage of the intrinsic electrochemical behavior of electrospray, a sacrificial electrode is used to generate at the same time electrospr ...
