제목 Efficientively release controllable electrospun nanofiber using hydrogel microstructure
초록 One of important factors in drug therapy is control of drug release. In this study, our aim is release control using electrospun fibers and hydrogels. Polycarprolactone (PCL) which is a biodegradable polymer was used as fiber and the Polyethylene glycol (PEG) based hydrogel surround the fibers. Coaxial electrospinning was proposed as a one-step process for producing core-sheath nanofibers, which showed to prolong the time period of delivery effectively. However, single-nozzle electrospinning is more favorable than coaxial spinning, because a simple process and easy scale-up are essential requirements for reproducible production on a massive scale. The complex of electrospun fibers and hydrogel makes possible to control the release easily from single-nozzle electrospinning. Moreover we can fabricate microstructures such as microparticles using this method. So we expect this system will provide a new useful release system.
