Open channel-based microchip electrophoresis interfaced with mass spectrometry via electrostatic spray ionization

Hubert Girault, Natalia Gasilova, Liang Qiao, Yan Deng

The coupling between open channel-based microchip electrophoresis and mass spectrometry via electrostatic spray ionization is proposed for in situ detection of fractionated analytes. Electrophoretic separation is performed in an open channel fabricated in ...

Development of a microfluidic interface for suspended microchannel resonators

Damien Maillard

Suspended microchannel resonators (SMRs) are devices that detect particles in liquid samples. In comparison with similar resonating devices that must be immersed, SMRs allow the fluids to flow through microfluidic resonators. This principle of operation le ...

Droplet extraction module for the analysis of segmented flow generated by a neural probe

Philippe Renaud, Arnaud Bertsch, Guillaume Cédric Yves Petitpierre, Colin Darbellay

We recently developed a neural probe allowing to capture at high temporal resolution nano-volume droplets of interstitial fluid from the brain organized in a segmented flow. In order to enable the analysis of these small volume and low concentration drople ...

Random sampling of bandlimited signals on graphs

Pierre Vandergheynst, Rémi Gribonval, Gilles Puy, Nicolas Tremblay

We study the problem of sampling

k

-bandlimited signals on graphs. We propose two sampling strategies that consist in selecting a small subset of nodes at random. The first strategy is non-adaptive, \ie, independent of the graph structure, and its perform ...

Sample processing device with detachable slide

Martinus Gijs, Ata Tuna Ciftlik

A biological and chemical sample processing device that b. comprises a high pressure-resistant, shallow and wide area microfluidic chamber having at least one wall formed by a detachable slide containing samples such as immobilized entities, biological sam ...

Metropolis-Hastings sampling of paths

Michel Bierlaire, Gunnar Flötteröd

We consider the previously unsolved problem of sampling paths according to a given distribution from a general network. The problem is difficult because of the combinatorial number of alternatives, which prohibits a complete enumeration of all paths and he ...

Simultaneous measurement of liquid absorbance and refractive index using a compact optofluidic probe

Maurine Malak Karam Awadallah

We present a novel optical technique for simultaneously measuring the absorbance and the refractive index of a thin film using an infrared optofluidic probe. Experiments were carried on two different liquids and the results agree with the bibliographical d ...

Crossed fiber optic Bessel beams for curvilinear optofluidic transport of dielectric particles

René Salathé, Fabrice Merenda, Kyunghwan Oh

Due to its unique non-diffracting and self-reconstructing nature, Bessel beams have been successfully adopted to trap multiple particles along the beam's axial direction. However, prior bulk-optic based Bessel beams have a fundamental form-factor limitatio ...

Sampling and reconstructing diffusion fields in presence of aliasing

Martin Vetterli, Juri Ranieri

The reconstruction of a diffusion field, such as temperature, from samples collected by a sensor network is a classical inverse problem and it is known to be ill-conditioned. Previous work considered source models, such as sparse sources, to regularize the ...

Hybrid Raman/FBG-based Sensing for Simultaneous Point Dynamic Strain and Distributed Temperature Measurement

Marcelo Alfonso Soto Hernandez

We propose and experimentally demonstrate an integrated hybrid optical fiber sensing technique that combines distributed Raman-based temperature measurements with a time-domain approach for FBG dynamic interrogation using a shared optical source and receiv ...
