Biology, physics, applied mathematics and complex systems modelling
IdFsud gathers an important task force in biology, physics, applied mathematics and complex systems modelling. These disciplines synergize to develop innovative methodologies and tools in microscopy imaging and image analysis for applications in developmental biology, cell biology, plant biology, physiopathology and neurosciences. IdF Sud gathers three core partners with internationally acknowledged expertise: BioEmergences (CNRS-IBiSA), Imagerie-Gif and Polytechnique LOB (Lab for optics & biosciences, CNRS – INSERM).
The imaging facilities of IdFsud are developed and coordinated by: Nadine Peyrieras (INAF, CNRS, Gif-sur-Yvette), Béatrice Satiat-Jeunemaitre (I2BC, CNRS, Gif sur Yvette), Emmanuel Beaurepaire (Ecole Polytechnique, CNRS, Palaiseau).
The activity of the Ile-de-France Sud node (IdFsud) consists in developing novel optical biological imaging methods, in giving access to a broad range of imaging approaches to a large community, and in providing adequate training in light microscopy and CLEM.

The cell biology pole Imagerie-Gif is localized on the CNRS campus of Gif sur Yvette, in a new building dedicated to platform activity. This IBiSA platform provides efficient access to high quality services and state of the art technologies. It is open to the whole academic scientific community and to industrial partners. The management and development of this pole is under the responsibility of the team “Dynamics of cell compartmentation” (group leader B. Satiat-Jeunemaitre, Institut des Sciences du Végétal, Gif sur Yvette). It uses cell biology approaches and multiscale imaging (cytometry, bio-imaging and electron microscopy) to explore the cell. The development of new protocols and the mastering of update imaging approaches are part of the R & D objectives of the platform. Those are then transferred to platform services and disseminated through numerous training and teaching events, and opened to the whole scientific community. The cell biology pole of Imagerie-Gif activities contributes to the working groups “super resolution”, “Probe development” and “CLEM” within the France-BioImaging consortium.

R&D team: LOB
Head: Emmanuel Beaurepaire
Ecole Polytechnique is an internationally attractive institution combining research, teaching and innovation. Laboratory for Optics and Biosciences (LOB) is affiliated with the French Research institutions Inserm and CNRS, and Ecole Polytechnique. The Laboratory employs researchers with expertise in optics, molecular and cellular biology with the aim to explore new concepts and methods. Two LOB research teams are involved in optical imaging developments co-funded by France BioImaging.

NanoBio Team @ ISMO (CNRS/ Univ. Paris Saclay)
R&D team: NanoBio Team @ ISMO (CNRS/ Univ. Paris Saclay)
Head: Sandrine Lévêque-Fort
The Imaging group within the Nanobio team is composed of 8 people, with 1 CNRS researcher, 1 MCF, 4 PhD students and 1 engineer on temporary contract. The team develop new fluorescence imaging microscopy modalities for live cell imaging, FLIM and super-resolution.
For most biological questions, it is essential to monitor in vivo and in real time the complex cellular machinery with extreme sensitivity and ultimate resolution. The fluorescence thus remains the tool of choice for specific monitoring in biology. Beyond imaging intensity to a specific location, fluorescence and its various spectroscopic properties can be used to locally probe its environment or reveal interactions. The photophysical properties of fluorophores are the basis of recent developments, which have enabled microscopy to turn into nanoscopy, exceeding the resolution limit imposed by diffraction, enabling the detection of single molecules with nanometer resolution. This level of resolution allows to consider the study of biological systems at a scale unprecedented in optical microscopy. The developments of the team aim to correlate functional and structural 3D information in different biological applications. In particular we develop different strategies to take advantage of supercritical angle fluorescence (SAF) emission and also introduced a time approach to localize single molecule in structured excitation (ModLoc)
