Netherlands Electron Microscopy Infrastructure
NEMI ensures access to the most advanced electron microscopy (EM) technologies for all researchers in the life and materials sciences.
Our mission is to accelerate innovations in EM, enabling novel applications of societal and economic importance.
What is Electron Microscopy?
Electron Microscopy (EM) allows us to see the smallest details, visualizing molecules and materials at the highest resolution. This capability is crucial for addressing critical issues in Life Sciences, such as understanding diseases like cancer and dementia, and in Material Sciences, such as developing nanomaterials to tackle challenges like climate change and biodiversity.
Life Sciences EM
EM is essential for exploring biological structures at both cellular and molecular levels. It has uncovered how human cells are compartmentalized by membranes, each with specialized functions that coordinate diverse processes. Innovations in cryo-EM, which operates at extremely low temperatures, allow us to view proteins and protein complexes in their native cellular environments at atomic resolution. This provides critical insights into disease mechanisms (e.g., cancer cell transformation, brain aging) and human development (e.g., stem cell differentiation and renewal).
Recent advancements in automated 2D (large-scale EM) and 3D (volume-EM) imaging have opened new possibilities for revealing cellular architectures within their complex environments, such as tumors and entire brains. Cryo-EM has not only revolutionized academic research but has also been embraced by the pharmaceutical and biotech industries. It bridges the gap between molecular and cellular research by covering a key resolution and spatial range.

Individual proteins within the native environment of the cell can be imaged by EM. Right panel: EM image color coding distinct compartments in the cell.
Materials Science EM
EM is unparalleled in imaging the atomic structure of materials with sub-nanometer resolution. It also maps chemical composition and electronic properties in 2D or 3D at the nanometer scale. These capabilities are crucial for research in various fields:
- Geosciences, Metallurgy, Catalysis, Semiconductors (Hard Matter): Detailed atomic characterizations.
- Polymeric Materials, Tissue Regeneration, Foods (Soft Matter): Insights into material properties.
- Colloids: Studying materials where soft and hard matter intersect.
By providing these detailed characterizations, EM supports advancements in diverse scientific and industrial domains.
EM for materials science. Nanomaterials are nowadays abundantly used in displays, batteries, and solar cells, and as catalysts for efficient conversion of energy resources. Characterization and development of these nanostructured materials requires imaging at the level of individual atoms, which can be achieved with the newest generation of aberration-corrected electron microscopes.
Our Network
NEMI’s infrastructure comprises a distributed network of local EM Nodes and unique Flagship Nodes. These nodes offer state-of-the-art EM technologies that require specific expertise and expensive equipment. Our network enables comprehensive imaging across various length, resolution, and time scales, integrating with light microscopy and proteomics.
What We Offer
- Advanced Instrumentation: Access to cutting-edge EM technologies.
- Training and Support: Assistance with experiment design and data acquisition.
- Data Solutions: Innovative tools for data analysis and storage through our dedicated IT group.
- Collaboration: A platform for enhancing interactions, collaborations, and best practice exchanges within the Dutch EM community.
Our Vision
NEMI is committed to providing the latest EM technologies to a broad user base, ensuring that The Netherlands remains at the forefront of EM research and development.
We develop faster microscopes capable of handling larger volumes and multi-modal microscopes that combine EM with other critical information such as omics, fluorescence, and X-rays.
Addressing Social Challenges
High-end EM infrastructure is essential for developing smart drugs and materials. By understanding their nanostructure, we can design solutions to pressing social challenges, including smart drug development and advanced material creation.

NEMI ensures access to the most advanced electron microscopy (EM) technologies for all researchers in the life and materials sciences.
Our mission is to accelerate innovations in EM, enabling novel applications of societal and economic importance.
NEMI is a network of regionally distributed nodes, each with specialized expertise and resources.
National Coordination: A national plan will coordinate the acquisition of the latest EM equipment and provide access to regional centers.
Strategic Partnerships: NEMI collaborates with Dutch and international companies and key projects such as NL-BioImaging AM (light microscopy), Instruct (structural biology), NanoLabNL (nanotechnology), NSEO (geoscience), and Health RI (personalized medicine and health).
The Central Access Node in Utrecht is the national central entry point, connecting users with the right imaging technologies through NEMI Nodes and offering key infrastructure insights.
Located in Delft, Eindhoven, Groningen, Leiden, Maastricht, and Utrecht, these nodes offer advanced and specialized EM techniques. Each node is supported by leading principal investigators and facility managers, ensuring optimal conditions for regional and national access. Flagship Nodes collaborate with Regional Nodes, sharing personnel and equipment to maximize efficiency and accessibility.
Many of NEMI’s responsibilities are entrusted to the Executive Board (EB), particularly in managing the day-to-day operations and overseeing the scientific and strategic direction of the organization. The EB is designed to represent the Dutch life and materials science EM communities. We aim to include one delegate per region, elected by the local community and approved by the General Assembly (GA). Each EB delegate is responsible for maintaining communication with the Regional and/or Flagship EM nodes in their respective regions. The EB meets at least four times a year, with its primary responsibility being the coordination of EM infrastructure, innovation, and access at the national level, as well as monitoring the progress of work packages. The EB reports annually to the General Assembly on NEMI’s progress through a detailed report.
The current EB members are:
- Judith Klumperman (UMCU, chair)
- Jacob Hoogenboom (TUD)
- Ron Heeren (UM)
- Dirk Slotboom (RUG)
- Bram Koster (LUMC)
- Friedrich Förster (UU)
- Heiner Friedrich (TU/e)
- Meindert Lamers (NeCEN)
Opportunities for Input
Stakeholders and interested parties have several opportunities to provide input to NEMI. Key avenues for engagement include:
- The annual NEMI Day: A dedicated event where participants can contribute ideas and feedback. Next NEMI day will take place 12 November 2024 in Delft.
- Conferences: Engagement during various scientific conferences where NEMI is represented.
- General Assembly at Dutch Biophysics: A key forum for interaction and input, coinciding with the DutchBiophysics meeting. Next meeting planned for October 7-8 2024 in Veldhoven.
Additionally, user groups exist for specific fields such as CryoEM, VolumeEM, and Materials Science. These groups offer further opportunities for involvement and connection with experts in these areas. Feel free to reach out to these groups to engage more deeply with NEMI’s activities.
