pH prediction and control in bioprocesses using mid-infrared spectroscopy

An on-line pH monitoring method based on mid-infrared spectroscopy relevant to bioprocesses is presented. This approach is non-invasive and does not require the addition of indicators or dyes, since it relies on the analysis of species of common buffers us ...

Luminescent lanthanides bioprobes emitting in the visible and/or near-infrared ranges

Steve Comby

This Ph.D. work deals with the development of lanthanide-based bioprobes for biomedical analyses and imaging. For this purpose, two different approaches have been followed, one focusing on visible-emitting complexes, while the second addresses the sensitiz ...

Capillary electrophoresis immunoassay using magnetic beads

Hubert Girault, Anne-Laure Gassner, Hong-Xu Chen

Protein A-coated magnetic beads (0.3 μm) have been trapped in a small portion of a neutrally coated capillary (50 μm id). Anti-β-lactoglobulin (β-LG) antibodies have then been immobilized on the beads through strong affinity with protein A to subsequently ...

A Novel Strategy for the Design of 8-Hydroxyquinolinate- Based Lanthanide Bioprobes That Emit in the Near Infrared Range

Jean-Claude Bünzli, Caroline Vandevyver

A new polydentate tripodal ligand T2soxMe was synthesized to take advantage of the chelating effect of tridentate 8- hydroxyquinolinate subunits. Potentiometric and spectrophotometric titrations reveal seven pKa values of between 3.7 and 10.2. In water, th ...

Linking chemical speciation to metal bioavailability

Cristina Lamelas

It is recognized that dissolved organic matter (DOM) plays an utmost role in aquatic ecosystems by binding trace metals and influencing their speciation, bioavailability and detrimental effects. DOM is considered to protect the aquatic microorganisms from ...

Metal-based chemosensors for amino acids, peptides, and nucleotides

Andrey Buryak

An organometallic 4d transition metal complex [CpRhCl2]2, together with commercially available dyes, was used to construct indicator displacement assays (IDAs) for the detection of peptides, amino acids, and nucleotides. The combination of the CpRh compl ...

Supramolecular chemistry of 12-Metallacrown-3 complexes

Zacharias Immanuel Grote

12-Metallacrown-3 complexes were formed by self-assembly of organometallic half-sandwich complexes [(π-ligand)MCl2]2 (M = Ru, Rh, Ir) and 3-hydroxy-2-pyridone ligands in the presence of Cs2CO3 as base. Upon mixing of different macrocycles, reversible metal ...

A Starburst-Shaped Heterometallic Compound Incorporating Six Densely Packed Gd3+ Ions

André Merbach, Alain Borel, Eva Jakab Toth, Joao Bruno Livramento Fig.

The heterotritopic ligand [bpy(DTTA)2]8- has two diethylenediamine-tetraacetate units for selective lanthanide(III) coordination and one bipyridine function for selective FeII coordination. In aqueous solution and in the presence of these metals, the ligan ...
