Carles Justicia Mercader


The IIBB Microscopy Unit was created in July 1999 by the supervision of Joan Serratosa, Scientific Responsible until 2020. The Unit provides services and training to researchers from the IIBB, CSIC, Clinical Campus, and other public or private research institutes on optical microscopy and image analysis. It includes a set of state-of-the-art equipment and techniques to perform the experiments requested by the different research groups.  It also provides technical assistance from the design of experiments to the analysis of the results obtained. This service is member of the Red Española de Microscopía Óptica Avanzada (REMOA).

To book any system of our Microscopy Unit write to Technical Responsible: carme.casal@iibb.csic.es or microscopia@iibb.csic.es . For the first session you have to do a technical training by microscopy staff. When you are proficient with equipment you can book them as a self-service.

All users are required to comply with Health and Safety policies and procedures of the IIBB-CSIC.


The Microscopy Unit of IIBB is located at 6th floor of the building. Our microscopy systems are available 12 hours a day, from 8h to 20h, 5 days a week, to all scientists working at Campus Clinic. To perform over-weekend experiments please contact our microscopy staff.

External scientists and companies have to send an official request to carme.casal@iibb.csic.es or microscopia@iibb.csic.es.



- Read and respect the rules and instructions of microscopes usage.

- Leave the equipment and material clean and protected after use.

- Notify the technical staff about any incident or problem observed.

- Respect safety rules.



A 30% discount will be applied for over-night/over-weekend live imaging experiments.

Late cancellation (< 24h in advance) will result in billing if the time slot is not reserved by another user. This is no applicable to live imaging experiments.
