Maastricht MultiModal Molecular Imaging Institute

The Maastricht MultiModal Molecular Imaging Institute (M4I) is a state-of-the art molecular imaging institute that brings together a powerful palette of high-end, innovative imaging technologies. The mission of the institute is to perform fundamental, instrumentation and applied studies in molecular imaging as a part of a translational, synergistic, interdisciplinary research programme. M4I aims to be a leading international molecular imaging center relevant for science, education, economy and society.  The institute aspires to generate a high-end research environment and a unique knowledge infrastructure, attractive to top researchers from all over the world.

A Brightlands institute

Brightlands logo

Brightlands is an open innovation community in a global context, connecting four campuses in the province of Limburg: in Maastricht, Heerlen, Sittard-Geleen and Venlo. The campuses provide entrepreneurs, scientists and students state-of-the-art facilities to support development, education, innovation and growth. Naturally, there are close links between all four Brightlands campuses, and together they enable Limburg to serve as an innovation region where researchers and entrepreneurs take on the major challenges in the areas of materials, health, food and smart services.

Two M4I Divisions

M4I | Division of Nanoscopy
Strives for greater insight into the 3D form of cell proteins, paving the way for developing more effective treatments for diseases such as cancer and tuberculosis while gaining better understanding of how protein complexes manage healthy and diseased cells, allowing drugs and vaccines to work more effectively.

M4I | Division of Imaging
Mass Spectrometry

Developing and applying state-of-the-art mass spectrometry based molecular imaging approaches for nanomedicine and biomedical research, including mass spectrometry as a diagnostic and prognostic tool for personalized medicine in oncology, neurology and cardiovascular medicine.  Go to division of IMS


The M4I Division of Nanoscopy investigates cell structures at a macromolecular level. Inside cells, proteins work together in complex structures and are responsible for virtually all processes in the human body, including diseases such as cancer. To understand the working mechanisms of protein complexes, three-dimensional imaging of normal and disease-causing protein complexes is essential. This could ultimately lead to more effective treatments, but also to vaccines against diseases such as tuberculosis.

The M4I Division of Imaging Mass Spectrometry is one of the world leaders in high resolution molecular imaging of biological surfaces. The division targets the development and application of state-of-the-art mass spectrometry based molecular imaging approaches for biomedical cellular and tissue research. Main research aim for the coming years is to develop and apply mass spectrometry as a diagnostic and prognostic tool for personalized medicine.


M4I’s scientists will be involved in teaching at a bachelor's, master's and PhD level, within the University College Maastricht, the Maastricht Science Programme and various programmes within the Faculty of Health, Medicine and Life Sciences.

Access to facilities

Requests to access the Nanoscopy or Imaging Mass Spectrometry facilities of M4I can be specified using the 'Access to facilities'-contact form. The lab manager of the requested facility will evaluate your request.

M4I office wing

The M4I office wing has been designed with the same open and transparent look and feel as our labs. Based on C.O.R.E. collaborative open research education. C.O.R.E. requires a transparent and open environment for both laboratories and offices. M4I has invested heavily in an innovative and open environment for collaborative research. Research and office space is shared by scientist from very different backgrounds and disciplines, ranging from the fundamental sciences, technology and engineering as well as clinicians. In line with the CORE philosophy of Maastricht University the infrastructure is primed for researchers to cross the boundaries of their own disciplines and stimulate each other to excel in translational imaging science.

    Vitrojet, indispensable for electron microscopes

    Friday, November 2, 2018

    Thanks to cryo-electron microscopy, scientists can see inside cells, all the way down to the molecular level. This revolution makes it possible to analyze the precise composition of the many thousands of proteins. It might also reveal the mysteries of how diseases such as Alzheimer’s or tuberculosis develop.
