The study engineer will participate in a CNRS pre-maturation project on the selective bio-inspired filtration of biomolecules and viruses.
He will contribute to the development of polymer synthesis and functionalization of surface and nanoporous membranes for filtration and detection applications in the laboratory. Its role will be to control the manufacturing processes of oxazoline-based polymers and the grafting of these polymers onto surfaces by electrochemical voice. To do this, it will implement various ring-opening polymerization processes and various methods for the chemical characterization of surfaces, in particular XPS and scanning electron microscopy.
- Synthesizing and characterizing oxazoline based polymers
- Titration of the telemic functions of the polymers obtained.
- Demonstrate the structures obtained by SEC, NMR and Maldi-ToF
- Performing surface functionalization experiments using electrochemical processes. Optimize and adapt grafting methods to different conductive substrates and nanoporous membranes.
- Analyze electrochemically functionalized surfaces.
- To report in the form of reports and data sheets on the progress of the missions and to participate in the writing of articles or patents within the framework of the scientific project.
- Apply health and safety rules.
- Organize regular meetings with the various project participants.
- Organic synthesis
- Polymer synthesis
-Chemical characterization of macromolecules
- Characterization of surfaces and thickness measurements of deposited layers.
- English language: B1 to B2 (Common European Framework of Reference for Languages)
- To use the computer tools necessary for the piloting of the devices and the data processing.
Our CNRS pre-maturation project is based on the idea of mimicking a biological pore to strongly improve the filtration performance (selectivity, flow) of commercially available membranes. We are interested in intelligent, selective and efficient filters that have recognition properties and are able to adapt their permeability to passing molecules, as biological tissues and organisms naturally do.
This project is a collaboration between the groups of Fabien Montel (Laboratoire de Physique, CNRS/ENS de Lyon), Philippe Guegan (IPCM, Paris) and Jean-Christophe Lacroix (ITODYS, Paris).
The recruited engineer will be welcomed in the Polymer Chemistry team of the Institut Parisien de Chimie Moléculaire (UMR 8232). The research topics of this team are the control of polymerization, the construction of supra- and/or macromolecular architectures and the development of original (nano)materials. This work is very often carried out with industrialists for applications in many fields: biomedical, cosmetics, coatings, structural materials, but also in partnership with other university/laboratories with which this team develops innovative subjects.
The IPCM, in particular the polymer chemistry team, has all the necessary equipment for macromolecular synthesis (glove boxes, vacuum lines, etc.) and their characterization (SEC platforms, access to NMR and mass spectrometry platforms, nanoDSC, DLS, etc.).
The proposed position is intended to join Pr. Philippe Guégan's team in the laboratory located on the Pierre and Marie Curie site of Sorbonne University (Jussieu site). The engineer recruited in the framework of the project will spend some time in the team of Pr. Jean Christophe Lacroix of ITODYS (University of Paris) in the Molecular Electronics, Transduction & Nanoelectrochemistry department, where the research engineer will be responsible for the development of polymer grafting activities on surfaces under the authority of the head of the Nanoelectrochemistry team.
