Continuous sampling and analysis by on-chip liquid/solid chromatography

Philippe Renaud, Mario Schlund, Silvan Schnydrig

This paper describes a lab-on-a-chip device for continuous liquid/solid chromatography measurements. Chromatographic separations of phenolic test solutions as well as of vitamins are illustrating the ability and versatility of the system. The dependence of ...

On-chip liquid/solid chromatography for continuous analysis

Mario Schlund

This thesis reports on the development of technologies and methods for a microfiuidic device for continuous pressure-driven flow-injection analysis. Chip based, pressure-driven liquid chromatographic (LC) systems are often avoided due to the difficulties e ...

The affinity precipitation for the isolation of biomolecules

Gisela Stocker Majd

Product isolation increasingly becomes a major bottleneck in molecular biotechnology. This is especially the case for the sensitive proteineous substances (recombinant proteins, antibodies) and lately also DNA, usually produced in low concentration. The cu ...

Cp*Rh-Based Indicator Displacement Assays for the Identification of Amino Sugars and Aminoglycosides

Kay Severin, Andrey Buryak, Friederike Gundula Marie Zaubitzer

Indicator displacement assays based on the organometallic complex [Cp*RhCl2]2 and the dye gallocyanine have been used to sense aminosugars and aminoglycosides in buffered aqueous solution by UV-Vis spectroscopy. The data of three assays at pH 7.0, 8.0 and ...

Reversible sequential-binding probe receptor-ligand interactions in single cells

Rudolf Hovius, Horst Vogel, Marinela Gjoni Boillat, Jean-Manuel Segura, Christoph Schreiter

With the reversible sequential (ReSeq) binding assay, we present a novel approach for the ultrasensitive profiling of receptor function in single living cells. This assay is based on the repetitive application of fluorescent ligands that have fast assocn.- ...

Microscale total analysis system

Hubert Girault

The invention relates to an apparatus for performing chemical assays in an aqueous medium. The apparatus contains a reaction chamber(s) and a liquid in-flow channel connected to each chamber. The flow of liquid through the fluid in-flow channel to the reac ...

Micro ion analysis

Xiaoxia Bai

Due to the growing interest on micro total analytical system (μTAS), fast analysis of small amount samples with high throughout is highly desired. Conventional separation techniques, such as Liquid Chromatography, show a great potential for miniaturisation ...
