Electrospinning of drug-loaded polymer systems: preparation, characterization and drug release

摘要

In this paper we formulated and characterized biomedical devices for bone tissue regeneration. These systems were realized homogenously dispersing lamellar Hydrotalcite loaded with Diclofenac Sodium in a polymeric matrix of PCL (Poly-caprolactone). These biomedical devices were obtained through the electrospinning technique that has shown many advantages with respect to others techniques, in particular very interesting micro-fiber loaded with HDik were obtained. Drug delivery results were analyzed considering a mathematical modeling to evaluate the diffusivity coefficients.
