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.
The atomic force microscope (AFM) allows the analysis of living microorganisms in physiological conditions on the nanometer scale. The observation of bacteria in physiological aqueous medium necessitates a robust immobilization of the bacterium to the surf ...
Understanding of cells has mainly been achieved through analysis of average properties of large cellular populations. The increased awareness of cellular heterogeneity in various biological systems, spans from single bacterial cells to human tissue calls f ...
Fast and label-free techniques to analyze viruses and bacteria are of crucial interest in biological and bio-medical applications. For this purpose, optofluidic systems based on the integration of photonic structures with microfluidic layers were shown to ...
In the wild, bacteria are predominantly associated with surfaces as opposed to existing as free-swimming, isolated organisms. They are thus subject to surface-specific mechanics, including hydrodynamic forces, adhesive forces, the rheology of their surroun ...
Chlorinated ethenes solvents (CEs) are one of the most common contaminants identified in groundwater ecosystems. Long used as a degreaser in industry, perchloroethene (PCE) and trichloroethene (TCE) are particularly persistent in the environment as recalci ...
Flagellated bacteria, such as Escherichia coli, perform directed motion in gradients of concentration of attractants and repellents in a process called chemotaxis. The E. coli chemotaxis signaling pathway is a model for signal transduction, but it has uniq ...
Bacteria have evolved a wide range of sensing systems to appropriately respond to environmental signals. Here we demonstrate that the opportunistic pathogen Pseudomonas aeruginosa detects contact with surfaces on short timescales using the mechanical activ ...
Chlorinated ethenes, frequently encountered contaminants in groundwater, are often found to be incompletely dechlorinated to dichloroethene and vinyl chloride, more toxic products that accumulate in the aquifer. Some of the concerns in designing remediatio ...
The present invention concerns a geosynthetic element (1) for a geotechnical engineering application. The geosynthetic element (1) comprises: bacteria carriers (3) for carrying bacteria arranged to be propagated from the geosynthetic element (1) to a surro ...
ATP is a key molecule of cell physiology, but despite its importance, there are currently no methods for monitoring single-cell ATP fluctuations in live bacteria. This is a major obstacle in studies of bacterial energy metabolism, because there is a growin ...
