Abstract
Apatite scaffolds with complex porous macro- and micro-structures have been obtained by controlling the freezing of ceramics slurries and then performing ice sublimation and sintering. Architectures and mechanical properties of hydroxyapatite (HA) and biomimetic Sr-substituted hydroxyapatite (SrHA) scaffolds have been compared, pointing out the influence of the stoichiometry of the apatite on the final features of the synthetic bone substitutes. Biomimetic apatites are per sé systems delivering and releasing in situ ions with specific biological functions (Sr is an anti-osteoporotic ion). An antibiotic release can be associated to this intrinsic delivery function. A high performance liquid chromatography (HPLC) method exploiting an anionic column and a pulsed amperometric detector (PAD) has been developed and validated to follow the tobramycin release from an apatite-based system into a simulated body fluid (SBF).
