On-demand workflow design for image processing and analysis

Photomanipulation of biological objects (photoablation on spinning disks and on confocal equipped with 2photons, optogenetics)

Multiscale imaging of complex 3D objects: from embryonic to subcellular imaging (adaptive confocal and two-photon microscopy, light-sheet imaging of cleared tissues; NIR detection of luminescent probes, IA-based image analysis)

Multiscale measurements of molecular dynamics in cell and tissue (SPT, FCS, tICS, AiryScan, SIM, STED, SMLM, , Live SR, FRAP, live confocal imaging, Live TIRF and optogenetics)

We combine latest developments in cryo sample preparation and imaging by electron microscopies (cryo-FIB/SEM and cryo-TEM) to observe biomolecules of interest (ribosomes, carboxysomes, viruses, nuclear pore complexes…) within their cellular or tissular environment. Using cryo-electron tomography followed by image analysis, we are able to determine their 3D structures with near atomic resolution. Altogether, these methodologies pave the way for in situ structural biology studies.

Gene expression, DNA damage, DNA structure and DNA-binding proteins structures, super-resolution (SMLM, RIM, SIM, Airyscan), single particle tracking, photo-manipulation, Correlative Light Electron Microscopy (CLEM)

Atomic force microscopy on living cells or 3D samples is a powerful technique to measure the mechanical properties such as elastic moduli , rigidity, adhesion force, adhesion energy. Combining optical images, AI and AFM, cell population’s mechanome becomes accessible. 3D samples (tissues, organoids) mechanical properties require specific expertise we also provide.

Quantitative measurement of intracellular forces on living cells, but also within tissues (Drosophila, pupae, mouse intestines). Mechanotransduction, micro-nanorheology. High-resolution fluorescence imaging using remote focusing coupled with force measurements.
