Call for applications
Microorganisms play a central role in enabling and modulating key life science processes. Even in systems not primarily driven by microbial activity, such as photosynthesis or neural signaling, microbial-scale interactions exert a decisive influence. To advance our mechanistic understanding of these processes, it is essential to investigate functional hotspots at the microbial scale. These hotspots include root nodules, pathogen infection sites, biofilms, polymer interfaces, microplastic binding zones, and microscale regions within functional brain or kidney cells, drug release sites within tissues and many more. In each of these examples, critical biological functions depend on localized phenomena, such as the growth of a hypha into a plant host, morphological changes in cancer cells, or the precise location of drug action within tissue. Unraveling the dynamics at these microscale interfaces is key to unlocking deeper insights into life science processes.
Exemplary measurements at different scales

With this call, we invite research groups of the TUM School of Life Sciences to apply for participation in the NanoSIMS Synergy Month. This new initiative is aimed at strengthening interdisciplinary collaboration and advancing the One Health framework through high-resolution ion mass spectrometry. Based on the selection criteria listed below, selected projects will receive dedicated measurement days at the NanoSIMS laboratory, enabling in-depth analysis of microbial and biochemical hotspots in biological tissues and emerging materials. The application requires participation in the mandatory workshop program (one half-day pre-measurement and one post-measurement workshop). Only user groups that commit to disseminating the generated project results are eligible. Measurement days will be awarded on a first come, first served basis every two weeks until the application deadline.
We welcome proposals from all disciplines within the School that seek to explore microscale processes and contribute to a mechanistic understanding across human, animal, plant, and ecosystem health.
Got a cool project idea? Get in touch early!: If you believe your project could be a good fit, please contact us as soon as possible. We evaluate proposals on a rolling basis, so there's no need to wait until the final deadline. Early contact allows time to clarify details and begin sample preparation without delay. Further information is also available here: Technical information, sample preparation, and terms of use.
Final submission deadline: 15 February 2026
Total availability: 25 measurement days for about 5 different research projects
Eligibility: Research groups affiliated with the TUM School of Life Sciences
The proposal should provide a summary of the proposed research application including resources and planned steps of sample preparation and data analysis (max. 3 pages). In addition, the number of required measurement days and any support based on additional funding (advantegeous) should be listed. A support letter from the team PI must be included.
Submit your proposal to: https://syncandshare.lrz.de/preparefilelink?folderID=2AGi1WJh7G3uy2f1JjCR8 (For the password please see the cellulose fibril bundles in the scal graph at the bottom of this page)
The proposals will be evaluated and ranked by an independent panel of reviewers independent of the TUM School of Life Sciences based on the following selection criteria: excellence of the research approach, novelty within the respective field, technical applicability and feasibility, potential to inspire further studies and initiate new third-party funding opportunities, and the diversity of application areas.

NanoSIMS Synergy Month workshop program
- Pre-measurement workshop (Mandatory for all participants, provides essential guidance on experimental procedures and sample preparation): Wednesday, 18th March 2026 starting at 9 am, room to be confirmed
- Post-measurement workshop (Mandatory for all participants, focuses on advanced techniques of NanoSIMS data analysis and the inter-disciplinary discussion of pre-liminary results of participating projects to support the integration of NanoSIMS results into broader research context): Thursday, 30th July 2026 starting at 9 am, room to be confirmed
This initiative is made possible through the generous support of the departments within the TUM School of Life Sciences.
