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 use magnetic microbeads, which are magnetically self-assembled in chains in a microfluidic chip, as reaction substrates to implement two different sandwich immunoassay protocols for the detection of mouse monoclonal target antibodies. The magnetic chain ...
[...] During this project, the fusion feasibility of chips produced for other applications have been tested and some critical fusion parameters have been defined. Then, with the help of FEM simulations, a new chip design has been proposed to overcome the p ...
This paper describes a simple system for the actuation of a biological fluid through micro-channels with a thermoactivated polymer actuator. This system is of interest for the development of single-use diagnostic test-strips since the actuation of the samp ...
Since the introduction of the of Micro Total Analysis Systems concept in 1990, important progress in microfluidic analytical systems has been realized. In many cases, microfluidic systems have shown improved analytical performances over classical methods, ...
In this letter, we present a reconfigurable reflectarray cell operating at 12 GHz and fabricated in a monolithic MEMS process. A 5-bit digital control allows reconfiguration of the reflection phase over the full 360deg range, while alleviating the impact o ...

This thesis reports on the development of technologies and methods for a microfiuidic device for continuous pressure-driven flow-injection analysis. Chip based, pressure-driven liquid chromatographic (LC) systems are often avoided due to the difficulties e ...
Pico-second time-resolved time-correlated single photon counting (TCSPC) technique under the total internal reflection (TIR) condition has been used to study the photophysical properties of Coumarin 343 (C343) dye molecules adsorbed at the water/1,2-dichlo ...
Microstencil lithography, i.e. local deposition of micrometer scale patterns through small shadow masks, is a promising method for metal micropattern definition on polymer substrates that cannot be structured using organic-solvent-based photoresist technol ...
We review the phenomena having an impact on the interaction between light, paper and color halftones. They comprise surface reflections and refractions at the air-paper interface, propagation of light within the paper, internal reflections at the paper-air ...
This article presents the first example of a microfluidic chip for heterogeneous bioassays using a locally immobilized biospecitic layer and operated electrokinetically. The reaction chamber has picoliter dimensions and is integrated into a network of micr ...
