Topic description
Ce projet aborde plusieurs aspects scientifiques des biomatériaux : modification chimique, formulation, physico-chimie et interactions cellules-matériaux. Notre objectif est de réaliser des modifications chimiques sur le collagène de type I en phase aqueuse et dans des conditions non-dénaturantes par l'utilisation des voies de synthèses connues (ECD-NHS, bases de Schiff, chimie click, etc.) pour fonctionnaliser le collagène avec des entités spécifiques. Nous souhaitons étudier la modification chimique de collagène au niveau moléculaire ainsi que fibrillaire afin de concevoir des biomatériaux stimulables en réponse à des variations environnementales spécifiques, telles que la concentration en sucre ou l'irradiation. Des caractérisations profondes (chimique, physico-chimie et mécanique) seront menés pour établir la relation entre la chimie utilisée et le comportement finales des matériaux. Les matériaux obtenus seront soumis en contact avec les cellules afin d'étudier les comportements cellulaires dans différentes conditions (avec ou sans exposition à des stimuli), pour finalement comprendre l'interaction entre cellule et matériau.

This multidisciplinary project covers several scientific aspects of biomaterials: from chemical modification, formulation, physico-chemistry, to cell-material interactions. We aim at performing chemical modifications on type-I collagen in aqueous phase and non-denaturing conditions by using the chemistries that are known for collagen modification (like ECD-NHS, Schiff-base, click chemistry,…) decorate collagen with specific functional entities. Moreover, we intend to address both modification at the molecular and at the fibril levels, anticipating to engineer biomaterials that exhibit adaptive behavior in response to specific environmental changes such as sugar concentration, light irradiation. In-depth characterizations (chemical, physicochemical, and mechanical) will be conducted to establish the relationship between the chemistry used and the final behavior of the materials. The obtained materials will be submitted to cell culture to study cell behaviors at different conditions (with or without stimuli-exposure), to finally understand the cell-material interaction.
