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.
This dissertation reports on the development of devices and concepts for electrical and microfluidic cell manipulation. In the present context, the term cell manipulation stands for both cell handling and cell modification. The combination of microfluidic ...
An apparatus for manipulating fluid samples comprises a micro-chip device having first and second covered channels, each channel having openings at both ends. The channels intersect to form a common intersection. Three of the openings of the channels are c ...
In order to improve the throughput of the traditional “Two Electrode Voltage Clamp” (TEVC) measurements on Xenopus oocytes, we present here a chip-based non-invasive technique for the measurement of ion channels activity. We focus especially on the integra ...
We present a technology for the fabrication of three dimensional microfluidic channels in optically transparent substrates consisting of polymers with different properties. The microstructures are fabricated using polymer replication techniques with a view ...
In analytical separation technology there is a great demand for faster and more effective separation process. Miniaturization is a suitable technique for satisfying this demand because the reduction of the separation systems in size would give increased se ...
We present a technology for the fabrication of three dimensional microfluidic channels in optically transparent substrates consisting of polymers with different properties. The microstructures are fabricated using polymer replication techniques with a view ...
Bubble-free electroosmotic flow (fr-EOF) of aqueous electrolytes in microfluidic channels with integrated electrodes is demonstrated. Undesirable electrolytic bubble formation is avoided by applying a periodic, zero net charge current to generate a nonzero ...
We developed high-density microfluidic chips that contain plumbing networks with thousands of micromechanical valves and hundreds of individually addressable chambers. These fluidic devices are analogous to electronic integrated circuits fabricated using l ...
This paper describes the development of polyimide-based microfluidic devices. A layer transfer and lamination technique is used to fabricate flexible microfluidic channels in various shapes and with a wide range of dimensions. High bond strengths can be ac ...
