Piezoelectric suspended microchannel resonators

Damien Maillard

The objective of this PhD thesis is the development of a microfluidic platform for the real-time measurements of the mechanical properties of biological analytes at the single entity level. The systems developed for these purposes consist of piezoelectrica ...

Toward Microfluidic Label-Free Isolation and Enumeration of Circulating Tumor Cells from Blood Samples

Philippe Renaud, Margaux Catherine Marie Duchamp, Benoît Xavier Emmanuel Desbiolles, Camille Alice Raillon

The isolation, analysis, and enumeration of circulating tumor cells (CTCs) from cancer patient blood samples are a paradigm shift for cancer patient diagnosis, prognosis, and treatment monitoring. Most methods used to isolate and enumerate these target cel ...

Microdevice-integrated immunoassays for Point-of-Care Therapeutic Drug Monitoring

Elena-Diana Bojescu

A significant number of drugs exhibit narrow therapeutic windows and high inter-individual pharmacokinetic variability. In such cases, Therapeutic Drug Monitoring (TDM) is compulsory in order to optimize the efficacy of the drug while avoiding adverse effe ...

PZE-transduced Suspended Microchannel Resonators for sensing applications

Annalisa De Pastina

This PhD thesis aims at developing a system which can measure the mechanical properties of fluidic samples in the picoliter range. The ultimate goal is the characterization of cancer cells and viscoelastic fluids (i.e. biological fluids), in order to study ...

Red Blood Cell Aging During Storage, Studied Using Optical Tweezers Experiment

Sylvia Jeney

This paper presents experimental and numerical studies of erythrocyte stretching, with a focus on the aging of red blood cells in an in vitro environment during storage. The experimental studies were performed using optical tweezers. The laser beam was use ...

Image-Derived Input Function from the Vena Cava for 18F-FDG PET Studies in Rats and Mice

Rolf Gruetter, Bernard Lanz, Carole Poitry-Yamate

Measurement of arterial input function is a restrictive aspect for quantitative 18F-FDG PET studies in rodents because of their small total blood volume and the related difficulties in withdrawing blood. METHODS: In the present study, we took advantage of ...

Influence of Blade Aspiration on the Flow Quality of an Annular Axial Compressor Cascade

Peter Ott, Elia Colombo

Experimental and numerical investigations were performed in order to develop a technique of active flow control by aspiration applied to an annular axial compressor cascade. Continuous aspiration is applied through shaped slots located on the suction side ...

Assessment of the effect of haematocrit-dependent arterial input functions on the accuracy of pharmacokinetic parameters in dynamic contrast-enhanced MRI

Nathalie Just

The detection and prognosis of prostate cancer in its early stages are critically important. It is therefore essential to improve the existing dynamic contrast-enhanced MRI (DCE MRI) techniques commonly used for the assessment of the tumour vascular enviro ...

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

Horst Arthur Vogel, Samuel Terrettaz, Solomzi Makohliso

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 ...

Synchrotron refractive-index microradiography of human liver cancer tissue

Yiming Li, Giorgio Margaritondo

Three human liver tissue samples (similar to 5 mm x 40 mm x 20 mm) were excised from a cancer patient's liver during surgery. The microradiology analysis was performed with a non-standard approach on a synchrotron. High-resolution refractive-index edge-enh ...
