Compact portable biosensor for arsenic detection in aqueous samples with Escherichia coli bioreporter cells

Philippe Renaud, Harald Van Lintel, Nina Buffi

We present a compact portable biosensor to measure arsenic As(III) concentrations in water using Escherichia coli bioreporter cells. Escherichia coli expresses green fluorescent protein in a linearly dependent manner as a function of the arsenic concentrat ...

Distinctive Arsenic(V) Trapping Modes by Magnetite Nanoparticles Induced by Different Sorption Processes

Yuheng Wang

Arsenic sorption onto iron oxide spinels such as magnetite may contribute to arsenic immobilization at redox fronts in soils, sediments, and aquifers, as well as in putative remediation and water treatment technologies. We have investigated As(V) speciatio ...

Deposition and fate of arsenic in iron- and arsenic-enriched reservoir sediments

Janet Gordon Hering

Deposition of arsenic to the sediments of Haiwee Reservoir (Olancha, CA) has dramatically increased since March 1996 as a result of an interim strategy for arsenic management in the Los Angeles Aqueduct (LAA) water supply. Ferric chloride and cationic poly ...

Light induced etching of GaAs in a zinc atmosphere

René Salathé

N-type GaAs substrates have been exposed to zinc atmospheres at 600-800 deg.C and focused light from a Kr-ion laser at 647.1 nm. Etch pits are generated at optical densities of 0.2-10 KW/cm2 and exposure times of 5-60 minutes. They are characterised by a s ...
