Tungsten oxide thin films sputter deposited by the reactive gas pulsing process for the dodecane detection
2015
International audience; The DC reactive magnetron sputtering of a metallic tungsten target was performed in an argon + oxygen atmosphere for depositing tungsten oxide thin films. In order to control the oxygen concentration in the films, the reactive gas pulsing process, namely RGPP, was implemented. Rectangular pulses were used with a constant pulsing period T = 16 s whereas the duty cycle α (time of oxygen injection to pulsing period T ratio) was systematically changed from 0 to 100% of T. This pulsing injection of the reactive gas allowed a gradual evolution of the films composition from pure metallic to over-stoichiometric WO3+ɛ’ compounds. These WOx films were sputter deposited on comm…

PADDIAG: Plasmon-Acoustic Device for in vitro Diagnosis
2013
The aim of the project is to develop a plasmon-acoustic device for the real time detection of biomolecular interactions, in the prospect of cancer markers detection in blood samples from patients. In the context of early diagnosis, the detection of infinitesimal quantities of biomarkers is possible thanks to the breakdown of the equilibrium state of biochemical reactions. This could be obtained by the activation of the biological media using a system composed of a microdevice for generating acoustic waves coupled with a fluidic network. The latter system will be integrated on a detection device based on surface plasmon resonance. Here, we present design, realization and characterization of …
Characterization of the Breast Cancer Marker Candidate LAG3 Protein in Human Plasma by Direct SPRi-MALDI-MS Analysis from Antibody Arrays
2013
Proteomics plays an important role in biomarker discovery as prerequisite for later utilization. In this study, we coupled Surface Plasmon Resonance imaging (SPRi) with MALDI-TOF mass spectrometry to permit the multiplexed quantification of binding by SPRi and the molecular characterization of interacting partners by subsequent MS analysis. Hyphenation of the two technologies is applied to the detection and characterization of LAG3 (potential breast cancer biomarker) in human serum1.

A Continuous Time Pattern Recognition Retina
2002
International audience; We present in this paper a pattern recognition retina operating in continuous time. During a programming phase, the reference image is acquired by the sensor. After thresholding, the resulting binary image is stored in the sensor's pixels. During the recognition phase, the retina calculates, in an analog way and in continuous time, the zero displacement intercorrelation of the current image with the binary reference image and its complement. These two intercorrelation values are output as currents. By comparing these currents to expected values, determined during the programming phase, a shift of the pattern or a difference between the observed and programmed pattern…
