    Biogenesis mechanism of fat storage organelles

  • Quantitative biology on cells using microfluidic arrays. Charles Baroud (Polytechnique & Institut Pasteur). Biophysics Seminar ESPCI-ENS.
    

    Quantitative measurements on single cells are typically performed through flow cytometry, which yields high throughput data but only at a single instant on individualised cells. This leaves many unmet needs, such as following cell fate in time, looking at interactions between cells, or relating the cell behavior wit(...)
