Combined with high and ultra high pressure liquid chromatography, mass spectrometry-based peptide and protein structure analysis requires high resolution and mass accuracy achievable within short ion detection time. Although Fourier transform ion cyclotron ...
The synthesis, characterization, reactivity and in vitro anticancer activity of a series of Ru-II-arene complexes with carbohydrate-derived phosphite and biscarboxylato co-ligands are reported. The compounds were characterized by NMR spectroscopy and elect ...
The function of a peptide is intimately connected to its structure, which in solution is the result of the balance between non-covalent interactions within the molecule and the molecule-solvent interactions. Theory has the power to predict the properties o ...
A versatile microreactor protocol based on microfluidic droplets has been developed for on-line protein digestion. Proteins separated by liquid chromatography are fractionated in water-in-oil droplets and digested in sequence. The microfluidic reactor acts ...
Electrospray ionization mass spectrometry (ESI-MS) is a powerful tool to investigate large molecules. Miniaturized microchips, as a goal of ‘Lab-on-chip’, allow various integrated analysis quickly. The coupling of functional microchips and ESI-MS is capabl ...
We present the fabrication and operation of an integrated nano-electrospray thruster consisting of an array of microfabricated silicon capillary emitters and microfabricated silicon extractor electrodes. Based on previous work in which we showed operation ...
This review article summarizes the different fields of research at the Laboratoire d'Electrochimie Physique et Analytique at the Ecole Polytechnique Federale de Lausanne. The research areas covered include charge transfer reactions at soft interfaces, bio- ...
Nanoelectrosprays, well known for their use in sample injection for the mass spectrometry of large biomolecules, can also be used in other applications such as spacecraft propulsion. The thrust generated by a single electrospray emitter is well below 1 μN, ...
Current proteomic strategies depend strongly on the development of analytical methodologies and instrumentation. In parallel to the development of mass spectrometry (MS) - based proteomic workflows, microfluidic devices emerged in this field as a flexible ...
Metal ions are essential elements in all living systems. Their detections and identifications in biological processes require different methodologies. Mass spectrometry is one of the commonly used techniques in bioinorganic analyses to fulfill these requir ...
