characteristics of scaffolds can explain the delivery of gentamicinsulfate such as their porosity and their specific area [13]. Indeed,2CH-1BG scaffolds, having a larger specific surface area (7.9 m2g−1)and a larger pore volume (8.1 mm3g−1), release more gentamicinsulfate (with either 1 or 3%) than the two other types of scaffolds;followed by 1CH-1BG scaffolds and 1CH-2BG scaffolds. It has alsobeen reported in several studies that the nature of the antibioticwere involved in the kinetics of release [13]. Indeed, the gentami-cin sulfate presents an early release due to its hydrophilic character[13].For all scaffolds, the variations of the content of bioactive glassand that of chitosan do not impact the relaxation time. In contrast,the concentration of gentamicin sulfate increases the relaxationtime. The limit concentration depends on the content of bioac-tive glass and chitosan. The presence of a high content of chitosanincreases the limit concentration C0.These results are interesting because for scaffolds doped with1% or 3% of gentamicin sulfate, different behaviors are observed.Indeed, 2CH-1BG has a better kinetic of release that 1CH-1BG and1CH-2BG. The pore volume and surface area, due to the introductionof
