Offer Description

Metallic material functionalization with Extracellular Vesicles (EVs) is a desirable therapeutic approach to improve regenerative procedures. Due to their ability to transport/deliver bioactive molecules, scientific interest in the study of EVs has increased in tissue engineering and implantology. Evs functionalization of implants is depending on the ability of the surface to trap, preserve and released intact Evs. Our labs hypothesize that fabrication of nanostructures (bumps, peaks, cavities) at the scale of Evs (30 to 300nm) offers great opportunities for Evs functionalization. Engineering of various nanostructures on titanium-based implants made with ultrafast laser processes will be tested for their ability to trap, preserve, select Evs.

We have selected mesenchymal stem cells (MSC) and platelet derived EVs for titanium surface coating due to their demonstrated regenerative and immunomodulatory properties. The PhD project will consist in (i) assisting nanotextures fabrication, (ii) EVs production and characterization, (iii) evaluate Evs trapping/release efficacy and (iv) explore bio-functional effects (mainly in vitro and potentially in vivo).

The PhD student will work in a multidisciplinary environment, interacting with the Hubert Curien laboratory / Manutech USD platform (engineering of nanotextures) the Laboratory of Tribology and System Dynamics (LTDS) (surfaces metrics) and SAINBIOSE (bone and vascular teams) (EVs biology and in-vitro tests).
