Bio-inspired ceramics and composites
Bone substitution applications necessitate materials that are ideally:
- osseoconductors, or even osseo-inductors
- isoelastic with bone
- able to withstand mechanical loadings of a few MPa
Most existing bone substitutes are made from calcium phosphates ( (Hydroxyapatite, Tricalcium phosphate...). I2B studies means to improve these materials, by adding a polymeric phase (both for mechanical and biological functions). Bioactive glasses are also studied as filler in biocompatible polymers or as bone substitution scaffolds.
I2B deals with the processing of these materials, their chemical, mechanical and biological characterization (in-vitro and in-vivo tests) and the evolutions of their properties with time.
