Silanisation de polysaccharides en milieu liquide ionique et réactivité d’un organoalkoxysilane vis-à-vis de nucléophiles simples : vers des hydrogels injectables pour l’ingénierie tissulaire du cartilage ArchiMer
Guillory, Xavier.
Tissue engineering is a real challenge for the treatment of cartilage pathologies. In this field, biomimetic hydrogels based on natural polymers are among the most commonly used matrices. A hydrogel made of silanized hydroxypropylmethylcellulose (HPMC-Si) is especially promising because it can be injected in cartilaginous lesions by minimally invasive surgery. However, the current synthesis of HPMC-Si is limited by the insolubility of hydroxypropylmethylcellulose (HPMC). This thesis work was focused on finding new synthesis conditions for the design of HPMC-Si hydrogel. In order to obtain a complete solubilization of HPMC and to improve its functionalization by the (3-glycidyloxypropyl) trimethoxysilane (GPTMS), the use of ionic liquids (IL), which are...
