Balancing user support and innovation in a “hands-on users” cryoEM Research Infrastructure

The operational modes of electron microscopy core facilities can vary significantly, ranging from a purely service driven mode – where expert facility staff members handle all incoming samples and operate all instruments – to a strict hands-on user mode – where all researchers are enabled by staff members to actively operate the instruments required for their projects.

A strict hands-on user mode of operation comes with pros and cons: on the one hand, it allows researchers to actively drive their own projects, control experimental conditions independently and it provides researchers with valuable hands-on expertise that can be utilized in their future career steps. it also allows facility staff members to provide support that is tailored to user needs, typically leading to a more meaningful use of instrument time. On the other hand, this mode of operation requires facility staff members to dedicate a significant portion of their capacities to training and scheduling of newly incoming users and to create and maintain training documentation. In addition, it inevitably leads to instrument use by researchers who aren’t specialists (yet) in instrument optimization and troubleshooting.

We will discuss how the Central Electron Microscopy facility at Max Planck Institute of Biophysics strives to balance the pros and cons of such a hands-on user mode of operation, to optimize both quality and quantity of users’ results and how to balance innovation and continuity of electron microscopy workflows by close collaboration with soft- and hardware suppliers as well as facility users.
 

From development to service, opportunities for imaging facilities

Core facilities are vital for providing services to departments and stakeholders, but without innovation, they risk stagnation and failure to advance science. Core facilities are often based at discovery-based life science institutes, where development is a distinct activity and where a development project within a core facility is a temporary endeavor to produce a unique product, service, or result, turning a challenge into a solution. These projects vary in complexity, ranging from complete new imaging methods to protocol optimizations and technology adaptation.

For imaging core facilities, different opportunities for innovation do exist. Here, we will review different possibilities and focus on investigating comparative approaches for multiscale three-dimensional imaging. We showcase this approach with an example of murine lung vasculature from macro- to micro-structural level, comparing different imaging techniques and the results they yield. We believe that this is a crucial exercise for a core facility to be able to advise users on the best solution for their scientific projects. Consequently, we will highlight some aspects of our efforts to establish a data journey for our users and discuss our efforts to interact with other infrastructures, such as the Flemish supercomputing center, for that purpose.

Overall, we believe that establishing workflows and committing staff time to innovative/development activities that benefit the majority of users is essential for creating scalable development projects for long-term service implementation. A structured approach with a road map with go-and-no-go decisions and milestones can make this process transparent and tangible for the facility’s stakeholders.

Bridging the Innovation Gap: Industry-Focused Synchrotron XRPD Solutions for Pharmaceutical and Chemical Challenges

Synchrotron-based X-Ray Powder Diffraction (XRPD) is redefining structural analysis, providing the pharmaceutical and chemical industries with unmatched precision and capability for material characterization. This presentation will highlight how Excelsus Structural Solutions enables industrial customers to leverage advanced structural characterization by integrating synchrotron methodologies—without requiring them to navigate the complexities of direct facility access. Our innovations in XRPD methodologies achieve detection and quantification thresholds as low as 0.01%wt for crystalline phases in organic pharmaceutical compounds, making these capabilities readily available to industry partners, who can benefit from precise structural analysis without engaging directly with synchrotron instrumentation and technology. These advanced methodologies also allow for amorphous quantification without the need to spike the compound under investigation. By introducing refined calibration techniques—unaffected by inhomogeneous phase distribution within samples—our XRPD methodologies not only meet rigorous industrial standards for quantification but also exceed industry benchmarks.

The talk will showcase successful technology transfer, bridging gaps in knowledge exchange between complex research infrastructures and industry, and emphasizing real-world case studies. These examples demonstrate the impact of custom-tailored synchrotron solutions in overcoming industrial analytical challenges, enhancing both sensitivity and efficiency in structural characterization. The session will underscore how strategic research-industry partnerships not only advance technology transfer but also address critical needs in drug development and chemical analysis, accelerating innovation with practical, scalable solutions to develop higher-quality products.
 

Viventis Microscopy: Developing advanced light sheet microscope systems for live imaging of large multicellular systems

Petr Strnad

Viventis Microscopy Sàrl, Lausanne, Switzerland

Light sheet fluorescence microscopy (LSFM) is a preferred method for imaging living samples due to its high imaging speed and low phototoxicity. Organoids, which are 3D multicellular model systems that mimic the structure and function of organs in vitro, present a challenge for imaging as they develop over several days and grow to large sizes.

Viventis Microscopy was established to develop and commercialize light sheet microscope systems specifically designed for live imaging of such systems. To address the challenges of imaging large samples, SiMView, MultiView, and Panoramatic LSFM have been proposed. These systems use an identical concept: the sample is viewed from two opposing directions using two detection objectives and illuminated from two opposing directions using two illumination objectives. This setup increases the penetration depth by a factor of two for optimally sized samples. However, the sample must be held in a constrained space between the four objectives, making multi-position and organoid imaging difficult.

In collaboration with Prisca Liberali's group at FMI in Basel, Viventis Microscopy has developed an open-top dual-view and dual-illumination light-sheet microscope designed for live imaging of large specimens. This novel design overcomes the limitations of traditional setups. It is using two opposing detection objectives to image sample from two directions and two illumination objectives which are opposing but slightly rotated to point upwards. This creates an unobstructed linear space just above the two illumination objectives for a custom designed sample holders containing a linear array of wells and samples for multi-position imaging.
