Our mission

Our mission is to provide methods and instrumentation that cannot be maintained by a single research group. We focus on ion beam techniques for analysis and material modification, safe handling of radioactive isotopes as well as super-resolution microscopy.


Guided tour through the accelerator facilities of the RUBION, at the Ruhr-Universität Bochum.


Within the framework of the Network Particle World, a guided tour through the accelerator laboratory will take place on November 9, 2023, between 13:00 - 14:00 pm.

If you are interested, please register in advance for this free event under Registration.

We are looking forward to your visit !

Talenttage Ruhr 2023


On September 14th and 19th the super-resolution microscopy facility at RUBION in cooperation with the faculty for chemistry and biochemistry participated in the Talenttage Ruhr 2023. 4 small groups of interested kids and adolescents got to learn about fluorescence microscopy and how this technique can be applied to visualize brain cells. Participants had the opportunity to capture their own micrographs of living brain cells. Furthermore, we showed the participants how 3D printed parts can be used to build a low-cost smartphone microscope. Are you also interested to learn more about microscopy at RUBION? Send an email with your inquiry to rubion+nanoscopy@rub.de.

student project week 2023


On tuesday we had the opportunity to show 13 high school students, who participates in the student project week organized by the Faculty of Physics and Astronomy, around our microscopy labs. Our nanoscopy team showed the students how STED and SIC microscopes are constructed and what can be investigated with these microscopes. Among other things, we discussed resolution limits, cell skeletons, and fluorophores. We had a lot of fun giving an insight into our work and are already looking forward to next time!

Scanning Ion Conductance Microscopy

The RUBION nanoscopy research group works on, among other things, correlated STED and ion scanning conductance microscopy. Their thoughts and expertise on the setup and application of such correlated microscopes can now be found in form of a chapter in the newly published Springer Analytical Reviewś book 'Scanning Ion Conductance Microscopy' (Editor: Tilman Schäffer):

Optimization of Primary Neuron Cultures

In cooperation with the working group Electrobiochemistry of Neural Cells (Prof. Irmgard Dietzel-Meyer, Department of Biochemistry II) the working group Nanoscopy under the leadership of Heiko Leßlich has investigated methods for the optimization of primary cell cultures. Primary cell cultures from the rat brain represent an important model for basic research on nerve cells. Since a variety of different cell types exist in the brain, cell-cell interactions can complicate research. By adding substances that inhibit proliferation of certain cell types, cultures can be enriched with neurons. The effect of two cytostatic drugs on cell culture composition was evaluated using automated cell counting of micrographs. All study details and results can be found in the open access PLOS ONE publication (https://doi.org/10.1371/journal.pone.0265084). For further information contact Heiko Leßlich (heiko.lesslich@rub.de).

The RUBION team is mourning the loss of their dear team member Dr. Patrick Happel † 28.04.2021

Patrick Happel

With deep sadness and dismay we have to say goodbye to our dear Patrick.

Patrick always motivated us with his helpfulness and curiosity to go new ways. With great thankfulness we think of the many beautiful and exciting moments we could share with him.

You passed away much too early. You will always be remembered with many gratitudes.

The entire RUBION team would like to send our sincere condolences and deepest sympathy to his family, his close relatives and his circle of friends.

In silent mourning we say goodbye.

Reduced mode of operation in RUBION from 04 May 2020 in times of COVID-19

Ladies and gentlemen, defended users and guests of RUBION,

the corona crisis has the Ruhr-Universität Bochum (RUB) and thus also us in RUBION under control.

But there is also good news!

From 04 May 2020 we will reopen RUBION for you to give you the opportunity to resume your experiments or start new ones.

For this purpose the RUB has new regulations for a reduced operation mode. For the reopening and access to our facility, please contact our departments in advance.

Department RUBION-Ion beams (Building NT)



Department RUBION-Radionuclides (Building NI)


Furthermore, our colleagues are in home office and will be available for you via e-mail in the following days. You will find the e-mail addresses on our homepage.

Organization RUBION in times of COVID-19

Ladies and gentlemen,

defended users and guests of RUBION,

the corona crisis has the Ruhr-Universität and thus also us in RUBION firmly under control.
Therefore we are unfortunately forced to suspend the student education until further notice and to close RUBION as described below!

 The organisation in the RUBION area is organised as follows as of Wednesday 18 March 2020.

  • The operation in our department RUBION radionuclides (building NI) will be suspended until further notice after consultation with the radiation protection officers (SSB). This means that the SSB's are not available on site, but only during on-call duty (e.g. animal husbandry/care) in order to continue to guarantee operation from a radiation protection point of view.

  •  The operation in our department RUBION-Ion beams (building NT) will be stopped after consultation with the SSB's. For the time being, we will only maintain the ion implantation in the area of commercial operations (RUBION / rubitec GmbH). This means that the SSB's are alternately available on site and on call in order to guarantee the operation from a radiation protection point of view.

Furthermore, our colleagues are in home office and will be available for you via e-mail in the following days. You will find the e-mail addresses on our homepage.

With best regards and stay healthy
