Design and construction of a portable whole-cell living bacterial biosensor for the detection of arsenic in water

Nina Buffi

Contamination of drinking water with arsenic is a recurring problem in both industrialized and developing countries. Supplies for large populations can have concentrations much higher than the permissible levels, set by the World Health Organization (WHO) ...

Electrochemical As(III) Whole-Cell Based Biochip Sensor

Hubert Girault, Fernando Cortes Salazar

The development of a whole-cell based sensor for arsenite detection coupling biological engineering and electrochemical techniques is presented. This strategy takes advantage of the natural Escherichia coli resistance mechanism against toxic arsenic specie ...

Development of a microfluidics biosensor for agarose-bead immobilized Escherichia coli bioreporter cells for arsenite detection in aqueous samples

Philippe Renaud, Harald Van Lintel, Nina Buffi

Contamination with arsenic is a recurring problem in both industrialized and developing countries. Drinking water supplies for large populations can have concentrations much higher than the permissible levels (for most European countries and the United Sta ...

Miniaturized bacterial biosensor system for arsenic detection holds great promise for making integrated measurement device

Philippe Renaud, Harald Van Lintel, Nina Buffi

Combining bacterial bioreporters with microfluidics systems holds great promise for in-field detection of chemical or toxicity targets. Recently we showed how Escherichia coli cells engineered to produce a variant of green fluorescent protein after contact ...

TEM investigation on zirconate formation and chromium poisoning in LSM/YSZ cathode

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes, Josef Andreas Schuler, Zacharie Wuillemin

Cell durability is a crucial technological issue for SOFC commercialization, and considerable progress has been made in recent years. A number of degradation pathways have been established, amongst which microstructural changes, poisoning effects and forma ...

Localized Ion Implantation Through Micro/Nanostencil Masks

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Oscar Vazquez Mena, Cristina Martin Olmos, Philippe Langlet

A method is presented that allows the deﬁnition of micrometer- and submicrometer-sized implanted structures in silicon without using photoresist patterning. The process is based on the use of stencils as masks in a conventional ion implanter, and is tested ...

Biochip with E. coli bacteria for detection of arsenic in drinking water

Philippe Renaud, Thomas Michael Braschler, Harald Van Lintel, Jan Roelof van der Meer, Joël Theytaz

Arsenic and other pollutants are often present in trace amounts in drinking water in a number of countries. In aqueous solutions the sensitivity of arsenic- responsive bacterial bioreporters is far better than the performance of chemical field test kits. H ...

Biochip with E-Coli bacteria for detection of arsenic in drinking water

Philippe Renaud, Thomas Michael Braschler, Harald Van Lintel, Jan Roelof van der Meer, Joël Theytaz

Arsenic and other pollutants are often present in trace amounts in drinking water in a number of countries. In aqueous solutions the sensitivity of arsenic-responsive bacterial bioreporters is far better than the performance of chemical field test kits. Ho ...

Sulfur as pollutant species on the cathode side of a SOFC system

Jan Van Herle, Aïcha Hessler-Wyser, Josef Andreas Schuler

Sulfur poisoning in a strontium doped lanthanum cobaltite (LSC) cathode current collection layer was revealed in a solid oxide fuel cell (SOFC) tested in repeat-element and stack configuration. Sources of sulfur contamination, other than trace SOx in air, ...

The biouptake and toxicity of arsenic species on the green microalga Chlorella salina in seawater

The present study focuses on the biouptake, biotransformations, and toxicity of arsenic species on the marine green alga Chlorella salina in seawater from the Bulgarian Black Sea coast. Exposure to equal concentrations of As(III) or As(V) led to equivalent ...
