Popis: In situ tissue engineering requires to functionalize the surfaces of implants, to achieve better biocompatibility or to release pharmaceuticals. Often a burst release of such pharmaceuticals takes place and the surface functionality is gone rapidly. Casein-micelles (M-Cas) offer unique release capabilities for hydrophobic and hydrophilic substances. In this work, M-Cas were reconstructed and used as release system for curcumin as a model drug. Modified electrospun polycaprolactone (PCL)-fiber mats were coated with chitosan / tripolyphosphate nanoparticles (CS/TPP-NP) and functionalized with the reconstructed M-Cas. [1] CS/TPP-NPs and Na-caseinate (Cas) were used as blocking layer to slow down the release of curcumin loaded micelles. The layers were investigated by surface zeta-potential (ZP). The release of the curcumin from surfaces was possible and the blocking layers had a significant influence on the kinetics.
