Graph Chatbot
Chattez avec Graph Search
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 introduce for the first time a tuning mechanism for optofluidic devices by embedding a Micro-Air-Bag (MAB) actuator inside a microfluidic chip. Multiple tunable optical elements controlled through the pressure of compressed air were demonstrated. (C)200 ...

Purification of magnetic microparticles was demonstrated, with a purification efficiency of (72±14) % at a flow rate of 3 μl/min, in a microfluidic chip using a rotational magnetic system under continuous flow conditions. The rotation of a periodically arr ...
A novel UV-curable low-stress hyperbranched polymer (HBP) micromolding process is presented for the fast and low-temperature fabrication of hydrophilic microfluidic devices. Process, material and surface properties of the acrylated polyether HBP are also c ...
Low-cost and high-resolution on-chip microscopes are vital for reducing cost and improving efficiency for modern biomedicine and bioscience. Despite the needs, the conventional microscope design has proven difficult to miniaturize. Here, we report the impl ...
Optical trapping allows manipulating very small objects – varying from Angstöms to micron size particles – without physical contact by taking advantage of laser light. This technique, relying on light momentum transfer, allows manipulating biological matte ...
Magnetic microparticles and their application in bioanalytical microfluidic systems have been steadily gaining interest in recent years. This progress is fueled by the comparatively large and long range magnetic forces that can be obtained independently of ...
This paper reports on a new microfluidic chip designed for cell electrofusion. A pair of cells is brought into close contact by means of opposite dielectrophoretic forces and they are subsequently fused by applying a short electrical pulse. ...
Optofluidic dye lasers are microfabricated liquid dye lasers enabled by the microfluidics technology. The integration of dye lasers with microfluidics not only facilitates the implementation of complete "lab-on-a-chip" systems, but also allows the dynamica ...
The main aim of this project was to develop novel concepts for miniaturization of bioanalytical techniques for investigating biomolecular interactions. We used optical tweezers to selectively address individual biological objects in microfluidic channels. ...
Miniaturized system for bioanalysis have been constantly gaining importance and interest within the recent years. The reduction of sample consumption and reaction time are some of the major advantages of such lab-on-a-chip applications. One of the greatest ...
