X-ray absorption spectroscopy studies of the adducts formed between cytotoxic gold compounds and two major serum proteins

Angela Casini

Gold metallodrugs form a class of promising antiproliferative agents showing a high propensity to react with proteins. We exploit here X-ray absorption spectroscopy (XAS) methods [both X-ray absorption near-edge spectroscopy (XANES) and extended X-ray abso ...

Cancer marker detection in human serum with a point-of-care low-cost system

Sandro Carrara, Luca Benini

Chemiluminescence, i.e. the emission of light from a chemical reaction, offers interesting opportunities for developing point-of-care biosensors. However, commercially available systems are expensive, bulky, and primarily addressed to laboratory usage. The ...

Metal-Based Chemosensors for Important Bioanalytes

Sébastien Rochat

This work describes different strategies for the detection of biologically relevant analytes. The main goal was to achieve sensing in water, which is a prerequisite for application to real biological samples. In several cases, we could demonstrate that our ...

Reactivity of anticancer metallodrugs with serum proteins: New insights from size exclusion chromatography-ICP-MS and ESI-MS

Paul Joseph Dyson, Angela Casini, Michael Groessl

A method based on the coupling of high resolution size-exclusion liquid chromatography using a polymer stationary phase with inductively coupled plasma mass spectrometry was developed to study the interactions of two metallodrugs - cisplatin and RAPTA-T - ...

Metabolic Labeling and Protein Linearization Technology Allow the Study of Proteins Secreted by Cultured Cells in Serum-Containing Media

Supernatants from cell cultures (also called conditioned media, CMs) are commonly analyzed to study the pool of secreted proteins (secretome). To reduce the exogenous protein background, serum-free media are often used to obtain CMs. Serum deprivation, how ...

Conditional deletion of ferritin H in mice induces loss of iron storage and liver damage

Lukas Kühn, Friedrich Beermann, Liviu Vanoaica

Ferritin plays a central role in iron metabolism by acting both as iron storage and detoxifying protein. We have generated a ferritin H allele with loxP sites and studied the conditional ferritin H deletion in adult mice. Ten days after Mx-Cre induced dele ...

A synthetic membrane protein in tethered lipid bilayers for immunosensing in whole blood

Horst Vogel, Samuel Terrettaz, Solomzi Makohliso, Stéphanie Follonier

Tethered lipid bilayers, containing a transmembrane synthetic ligand-gated ion channel (SLIC), have been formed on gold surfaces. The SLIC was designed as a highly selective receptor and reporter protein to detect antibodies in whole blood, which are of im ...

On-chip thermopneumatic actuation system for coagulation time measurement

Philippe Renaud, Lynda Metref, Pierre Lemaire, François Bianchi

This work reports the demonstration of a thermopneumatic microfluidic actuator used to determine blood coagulation time. In this new system, the detection principle is the obstruction of a microfluidic channel by clotted blood. The sample actuation is done ...

Capillary electrophoresis hyphenated to inductively coupled plasma-mass spectrometry: A novel approach for the analysis of anticancer metallodrugs in human serum and plasma

Christian Hartinger, Michael Groessl

The development of metal-based chemotherapeutics lacks methods which are capable of providing early indication on the potential of new metal complexes as future anticancer drugs. Since most of these compounds are administered intravenously, serum proteins ...
