Structuration of biomaterials

J. Le Bideau, P. Abellan, S. Cuenot, H. Terrisse, S. Quillard

This activity concerns the conception and elaboration of biomaterials (injectable and thermo-sensitive hydrogels, hydrogel foams, cements) for tissue engineering applications. The main objectives are to determine their structure, and their mechanical and chemical properties at key interfaces in order to understand the biomaterial/cells interactions. This knowledge allows us to optimize the biomaterials’ chemical and topological characteristics. To reach these objectives, new methods based on atomic force microscopy (AFM) and cryogenic electron microscopy (cryo-TEM, cryo- FIB-SEM) are developed to characterize the biomaterials with high resolution. These  microscopies are used both in imaging and spectroscopy mode, along with vibrational spectroscopy (IR and Raman), DLS or zeta potential measurements.
