It is very difficult to obtain the coexistence of the macro-, micro-, and nanostructural properties necessary to mimic the organization of the human bone. To obtain all of these characteristics, we tested a supercritical fluid assisted technique for the formation of PLLA/ceramic scaffolds using hydroxyapatite (HA) nanoparticles loaded at up to 50% by weight of the polymer to improve the biomimethism and the mechanical properties of the scaffolds. We produced poly(l-lactic acid) scaffolds in relatively short time ( En ligne : http://pubs.acs.org/doi/abs/10.1021/ie8018752 [article] Nanostructured PLLA-hydroxyapatite scaffolds produced by a supercritical assisted technique [texte imprimé] / Ernesto Reverchon, Auteur ; Paola Pisanti, Auteur ; Stefano Cardea, Auteur . - 2009 . - pp. 5310–5316.
