7 imaging facilities and 17 R&D teams
The Paris-Centre node gathers biological imaging resources in the center of Paris, associating 7 imaging facilities and 17 R&D teams. The node Paris-Centre has the objective to make new developments and implementations of state of the art imaging systems, chemical probes and image processing for single molecules localization, dynamics and interactions in live cells, tissues and organisms and to perform cell functional analysis by using opto-manipulation. Paris Centre node was deeply involved in the “proof of concept” study led by the EurobioImaging ESFRI project.

UTechS UBI – Pasteur
Facility: UTechS UBI – Pasteur
Head: Jacomine Krijnse-Locker
Member of C2RT (Center for Resources and Research in Technology) the Unit for service and technology in ultra-structural bio-imaging (UBI) at Pasteur provides technical and scientific support in electron microscopy, mainly, but not exclusively, to the Pasteur community, analyzing host-pathogen interactions at the ultra-structural level. Our equipment enables us to do state-of-the-art EM for life sciences that includes three dimensional EM by tomography and focused ion beam SEM. The ultrapole is run by ten members (eight engineers and two technicians), each specialized in certain techniques. We put a big emphasis on correlate light- and electron microscopy to study key (rare events) of host-pathogen interactions and we have designed several protocols to combine room temperature LM and cryo-LM with FIB-SEM, cryo-SEM and cryo-tomography.
The UBI also has a small research group focusing on large DNA-viruses. Through this research theme we wish to establish and develop robust, new protocols for various EM-techniques.

Facility: PICT-IBiSA Curie
Head: Olivier Renaud (PICT-LM) & Daniel Levy (PICT-EM)
The Cell and Tissue Imaging Platform (PICT-IBiSA) of the Institut Curie brings together advanced microscopy technologies. Its main objective is to provide researchers in cell biology, development, structural, chemistry and biophysics with imaging approaches at different spatial and dynamic scales ranging from the molecule, to the cell, to the organism in healthy or pathological contexts.
The platform is organized around 3 poles: photonic microscopy, high-content screening, electron microscopy and cryo-electron microscopy. Photonic microscopy extends from dynamic imaging to high resolution. High throughput microscopy allows cellular screening of chemical and siRNA banks. Electron microscopy and cryo-microscopy provide the molecular structure and cellular ultrastructure of biological samples. The platform also offers expertise in data processing and analysis.
ImaChem – IBENS
Facility: ImaChem – IBENS
Head: Laurent Bourdieu
The Imachem imaging platform provides advanced light and electronic microscopy techniques to IBENS researchers and external users. Imachem is operated by 5 engineers. The main originality of IMACHEM is its ability to undertake innovative technical developments in optical microscopy and to make them available to all users. The first expertise of the platform is super-resolution microscopy, with the development of 3D-PALM using adaptive optic methods. It can perform ultra-structural imaging and single-particle tracking in 3D with a few tens of nanometers of spatial resolution. The second expertise is ultrafast two-photon microscopy for in vivo functional recordings with a temporal resolution in the msec range. A two-photon microscope using acousto-optic scanners for 2D scanning was first designed and installed in the platform. A new system providing ultrafast 3D scanning is currently under development. Additionally, electron microscopy using high-pressure freezing will be developed for correlative light and EM imaging.
UTechS PBI – Pasteur
Facility: UTechS PBI – Pasteur
Head: Spencer Shorte
Photonic BioImaging is a Unit of Technology and Service (UTechS) providing optical imaging expertise in life sciences and especially their application in studies on infectious biology.
Our activities include service rendering, training, technology-driven research and technology development. They are highly multi-disciplined, and collaborative, with the mission goal focused on the use of quantitative imaging and analysis to understand the processes of cell/tissue-biology, and their usurpation by infection and disease. The R&D is founded upon the need to develop optical imaging methods that bring new understanding of host-pathogen interactions and in situ high-content imaging techniques and their application to infection, cell biology, cellular microbiology, and microbiology. We work on novel techniques extrapolating quantitative information on spatiotemporal dynamics in situ and we push the limits of existing approaches aiming to enhance their performance thereby broadening their experimental utility.
