Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We present a novel image-based method to measure the on-chip microfluidic pressure and flow rate simultaneously by using the integrated optofluidic membrane interferometers (OMIs). The device was constructed with two layers of structured polydimethylsiloxa ...
Research on microfluidic devices for biological analysis has progressed sufficiently to be developed into point-of-care diagnostics products. The goal of this thesis is to improve multiple aspects of capillary-driven microfluidic devices. In particular, th ...
We present a novel optofluidic differential method for carrying out absorbance spectroscopy of subnanolitre volumes of liquid samples on a microfluidic chip. Due to the reduction of liquid volume, the absorbance detection in microfluidics is often hindered ...
Pressure lies at the basis of operation of most microfluidic systems, and is a determinant factor in the extent of miniaturization and in limiting the throughput and time constant of the microfluidic assays. Despite the apparent importance given to fluidic ...
High pressure-rated channels allow microfluidic assays to be performed on a smaller footprint while keeping the throughput, thanks to the higher enabled flow rates, opening perspectives for cost-effective integration of CMOS chips to microfluidics circuits ...
This thesis aimed at developing new 3D structuration techniques for a relatively recent new ceramic technology called LTCC, which stands for Low Temperature, Co-fired Ceramic. It is a material originally developed for the microelectronic packaging industry ...
We introduce a new low-temperature (280 °C) parylene-to-SiO2 bonding process with high device yield (>90%) for the fabrication and integration of high-pressure-rated microfluidic chips. Pull tests demonstrate a parylene-to-SiO2 bonding strength of 10 ± 3 M ...
We report the hydrothermal synthesis of free-standing lithium niobate nanowires. We show that the versatile properties of bulk lithium niobate such as nonlinear optical effects can be exploited at the nanoscale. We describe the fabrication of polydimethyls ...

We propose a simple microfluidic device for protein preconcentration based on the electrokinetic trapping principle. It comprises a narrow Nafion strip that is simply cut from a commercial membrane and is integrated into a molded poly(dimethylsiloxane) (PD ...
We report on a new structure of Dielectric Elastomer Actuators (DEAs) called zipping DEAs, which have a set of unique characteristics that are a good match for the requirements of electrically-powered integrated microfluidic pumping and/or valving units as ...
