Pushing the boundaries of the visible
Facility for Advanced Imaging and Microscopy
High-end light and electron microscopes, and cutting-edge imaging software and analysis tools
The microscopy and imaging core facility supports FMI scientists and collaborators for high-end light and electron microscopy, high-content screening, and image analysis.
Our main goals are to:
- Provide access to high-end acquisition and analysis workstations.
- Maintain instruments and workstations to ensure quality and efficiency.
- Train scientists to make sure hardware and software are used at the highest possible level.
- Develop workflows for big-data analysis and storage.
- Connect with other institutes to make usage of the know-how among the Swiss, European and worldwide network of microscopy and imaging.
Light microscopy (LM)
Light microscopes are available for a variety of purposes, e.g.: analyze and quantify molecular and cellular dynamics, (co-)localize labels, measure molecular interactions and concentrations. Our microscopes can accommodate a variety of samples, especially living specimen. We offer a very large palette of imaging modalities, from wide-field imaging to single-point and spinning-disk confocal, structured illumination, TIRF, slide scanning and 2-photon/NLO imaging. Expertise is available on any aspect of the entire process of experiment design, sample preparation and image acquisition.
Electron microscopy (EM)
We provide EM support for biological samples (cell or tissue) going to 2D classic transmission electron microscopy (TEM) for ultrastructure or immunolabelling investigations to 3D volume scanning electron microscopy (SEM) for connectomic. Dedicated to support FMI research groups, we are providing service and training from sample preparation to image analysis. Together with the FMI and Novartis structural EM team we are sharing since 2016 an EM facility that provides cutting-edge EM to a broad researchers community from academia and industry.
High content screening (HCS)
We offer support for HCS from assay development to image and data analysis. As HCS involves a new mindset to plan experiences, we are involved in the projects from the conception to the image analysis.
Image & data analysis
Acquisition at the microscope is just the first step to address biological questions. The acquired data must then be visualized and carefully analyzed to prove or reject the working hypotheses. Commercial software packages exist for visualization and generic quantification, but dedicated customized tools are needed for more complex analyses. Our task is thus to develop analysis modules, either as stand-alone tools or plug-ins for the commercial software, that specifically address our users' questions, and to offer continuous training on all our solutions.
