One year Post-doctoral position on hydrogels at Sorbonne Université

Dear everyone,

A one year post-doctoral position is opened for a joint project between two laboratories of Sorbonne Université: PHENIX (UMR 8234) and LCMCP (UMR 7574).

Sujet: Probing organisation and scaffold flexibility of hydrogels: a combined NMR and NMRD approach

Hydrogels are exciting soft permeable materials with a high potential for biomedical as well as food industry applications. We have at hand a well-characterized hydrogel system based on

charged polymers, showing strong sensitivity to the scaffold counterion [1] and presenting a possibility of incorporation of charged nanoparticles, such as clay nanoplatelets [2]. Regular stacking of clay nanoplatelets in the hydrogel paves the way to a highly interesting system with potentially anisotropic permeability. NMR based methods are to be used here to study firstly the scaffold flexibility (chain dynamics) using PFG-NMR. We wish to link scaffold flexibility to permeability of the hydrogels to guest

species. Secondly, nuclear magnetic relaxation dispersion (NMRD) will be used to probe the variety or environments accessible to water molecules. especially in the case of hydrogels with incorporated nanoparticles. This can clarify the availability of the nanoparticle surface for adsorption of guest species.

Expected start: December 2023
