ERA-NETs 2013 Interfacultary Centre of Biomaterials – Univ. Liège

  1. 1. Interfacultary Centre of Biomaterials – Univ. Liège www.ceib.ulg.ac.be 4 departements – staff ~ 30 p1. Polymer synthesis• biodegradable polyesters• functionalized poly(methyl)acrylate2. Polymer processing• Hydrogels• Film• Dispersed materials : micelles, nano-microparticles• drug immobilisation3. Analytical• Solubility, Mw determination• Stability, release kinetics study• Particle characterisation4. In vitro toxicity• Hemocompatibiliy 1• Animal cell tox
  2. 2. Particle Drug Delivery Drug formulationGENERALORGANISATION OF In vitro testingTHE RESEARCHPolymer synthesis Cell therapy – Tissue engineering In vivo testing VALORISATION : Patents – Close collaboration with industries – Analytical services 2
  3. 3. Biodegradable polyesters Macromolecular engineering with controlled polymerisation mechanism of cyclic monomers such as lactides, lactones. Novel architectures: block graft, random star-branched copolymers PolymerTECH : more than 300 different polymer samples available Material type : thermoplastics, hydrogels, amphiphilic gels Batch size : from g to 100 g ; in the near future : Kg scale facilities with reactive extrusion polymerisationSynthetic polyelectrolytes Living radical polymerisation of acrylic monomers Stimuli-responsive polymers. Functionalized polymers with reactive groups for synthesisof bioconjugates and fluorescent labelling of biomaterials. Strongly adhering polymers 3 Bulk polymerisation and purification in aqueous medium
