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.
The impedance of biological material changes with frequency, a phenomenon that has been discovered more than 100 years ago. It is due to the fact that the cell membrane acts as a capacitor which filters out currents at low frequency and lets them pass at h ...
Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...
A major problem in traditional cell culture methods, such as Petri dishes and culture flasks, is the very simplified artificial environment around the cells. Traditional cell culture methods lack features of the native cell niche, such as gradients and cel ...
The invention relates to various embodiments of a bioanalytical reagent with at least one vesicle, generated from a living cell, comprising at least one receptor, characterized in that a mechanism of signal transduction triggered by said receptor in the ce ...
Most of the biopharmaceuticals nowadays are produced by animal cells. The worldwide demand for a specific group of biopharmaceuticals, the monoclonal antibodies (mAbs), has significantly increased this last decade. The mAbs are used as therapeutics in part ...
The aim of this study was to gain a better understanding of orbitally shaken bioreactors (OSRs) operated without controllers for pH and dissolved oxygen (DO) concentration. We used cylindrical OSRs with working volumes ranging from 250mL to 200L to determi ...
This paper discusses the analysis of reflectarray cells comprising MEMS control elements. The method employed allows a very fast and accurate analysis of the reflectarray cell performance, quasi independently of the number of embedded MEMS and reconfigurab ...
Cell culture environment monitoring system (6) for monitoring parameters relevant to cell growth in at least one culture dish (4) containing a cell growth medium (14), including at least one sensing device (22, 22') configured to measure environmental para ...
We present an electrical impedance based biosensor on a microfluidic cell culture platform that enables label-free and re- al-time investigation of drug toxicity-induced effects on hepatocytes. The temporal evolution of the impedance at different frequenci ...
We present a novel perfusion-based microfluidic platform for label-free drug toxicity screening which can single out non-lethal morphological changes from cellular death using electrical impedance spectroscopy. Minor cellular changes such as cell-cell cont ...
