Microfluidic laboratory


The microfluidics laboratory of SOLEIL (MF Lab) is dedicated to the fabrication and analysis of microfluidic systems that are compatible with beamlines applications. It benefits to a wide range of scientific domains, from solid-liquid interfaces to chemical reactions, single cell studies or protein crystallography. The availability of a microfluidic lab in SOLEIL is an opportunity that enables designing and preparing microfluidic systems adapted to the beamlines that would like to perform this type of in situ analyses.

The laboratory is equipped with state-of-the-art fabrication and analysis tools, in a dedicated clean room. The laboratory is accessible to all members of SOLEIL, as well as to external members that have a running project at SOLEIL or are planning to. The day-to-day organization of the lab and instruments maintenance is carried out by the members of the lab, but each user is responsible for realizing its own devices according to its project. Acces to the lab is granted after training on each instrument.

More details about the laboratotory, tis instruments and the project going on can be found throughout this webpage.

Access to the lab

External users interested in the using the microfluidic lab should either contact the lab's responsible directly or a beamline scientist that is familiar with the lab. A short written notice describing the goals of the project and the instruments and ressources of the lab required might be asked for.

The fabrication of microfluidic devices, including their design and the choice of materials, is the responsibility of users, but the microfluidic team will be happy to orient and help to the best of its capabilities. Common and microfabrication-specific chemicals and consumables are available in the lab, but specific needs should be discussed in advance.

The everyday maintenance tasks of the lab are performed by the lab's assistant, but each user is responsible for taking care of its own experiments.

In House projects


This common project with the Proxima 1 (PX1) team deals with the development of micro-traps for the immobilization of microcristals and their study by ambient temperature and physiological conditions X-ray diffraction. This project is run by Igor Chaussavoine (PhD student), Pierre Montaville (post-doc) and Leonard Chavas (beamline responsible) on PX1 and Tiphaine Mateo (engineer) from the Microfluidic lab.



This project is run by the team of the SWING beamline and deals with the preapration and use of microlfuidic mixers that allow studying protein folding of nanoparticle synthesis by time-resolved Wide Angle X-ray Scatterring. This project is run by Thomas Bizien (beamline scientist) and Youssef Liatimi (beamline technician).


Sequential CO2 reduction:

This project is specific to the microfluidic lab and tries to develop microfluidic reactors for the sequential reduction of CO2 into valuable chemical or fuels. 3D-printed electrochemical and chemical microreactors set in line will be used to perform sequential, liquid phase catalytic reactions.

External collaborations


We have an active collaboration with Drs. Florent Malloggi, Corinne Chevallard and Patrick Guenoun to develop microfluidic cells adapted to IR and X-ray spectroscopies.


• Ecole Polytechnique, Biochemistry Laboratory:

We are collaborating with the team of Drs. Yves Méchulam and Thomas Simonson for the development of microfluidic mixers that can trap conformational intermediates in the RNA translation process.

• 13/07/2017: The Microfluidic lab, together with the PX1 team and the Biochemistry Laboratory at Ecole Polytechnique has been awarded an ANR Grant to develop microfluidic mixers fro the study of transient biochemical processes. Watch for the post-doc job opening!


• 10/06/2017: Tiphaine defended her first year project and recieved 18.5/20. Congratulations!
